HDPQ Plus & SP Operational Training

hello everyone my name is ross signal the director of product management and marketing with dranitz i'm joined in the room here uh two gentlemen you probably know by now um ken demario and thurman bridgers i'm ross over here uh we're trying a little different format today as you can see we have a webcam on the room itself we'll do a little bit of hands-on demonstrations as well so please be patient as we experiment with these new methods and also i want to share that our webcam's a little blurry on the right-hand side so we have a replacement on order so we apologize for that so anyway let's get started here uh again we have our technical support staff uh thurman and ken um they and all of us will be available during the meeting um for chats and questions and answers um so we will be monitoring the chat during our presentation today however just please be patient we'll try to stop at the appropriate times to answer questions but if we don't get your question uh we will definitely um attack all the questions at the end and review them so uh just please be patient with that our next training session uh will be on december 2nd we're going to take a week off for our thanksgiving here in the united states and that session will be our second module of our portable applications training last week we focused on generator testing and our drain expert in two weeks from today on december 2nd we're going to focus on the hdbq family it's ieee 519 2014 compliance testing uh vfd monitoring and dc circuit monitoring so similar to last week we're going to go through and show how to configure set up monitor and review data for these particular types of applications so if you have not registered please just go back to the same web page that you registered before to register for those web meetings okay the focus of today we are back doing our operational training of our hdpq family which includes the plus and the sp um we have a more detailed uh list and a couple slides of what we're going to cover but in general we're going to speak about how to set up the instrument we're going to demonstrate the automatic and the manual wizards review basically how to do basic analysis on the instrument and how to do analysis using our drainview software excuse me we're not going to get extremely detailed in any of these parts what we recommend for detailed setup information attend our our um application training and we'll focus on specific setups and how to use those we're happy to answer your questions today but the thing with the setups it's really application dependent you can have sort of a generic setup or for very specific applications like we're covering in other webinars so um you know if you have specific questions we're happy to answer them but we'll go into detail on the specific applications so again please chat your questions uh we have too many folks here to have a voice dialogue so we are monitoring the chats right now uh my suggestion is to please chat to everyone and uh ken thurman and myself will all see this and again we'll try to respond today or immediately on when we see some chats but certainly by the end so please be patient and today's web meeting like our others uh over the summer and in the fall is being recorded so we have our our webcast our media page on our website uh we'll post it on there with the other chats with the other uh presentations probably by the end of the week so if you have some colleagues who weren't able to attend this or maybe you weren't able to attend a prior session we have a list of recordings there maybe about eight or ten and we'll continue to build them so just a little bit about drainage for those of you who are new to our web training uh we are located in edison new jersey uh stone's throw from new york city you can see here's us in edison and here's manhattan right over here in uh non-cova times we'll say we had a lot of visitors who uh actually wanted to see new york city but did it under the guise of visiting granite so we're in a very convenient location within an hour of new york uh hopefully when uh covid comes down we'll be able to welcome people back here and you folks who want to travel and come back and visit us so we're at a very strategic location uh just a review of our product and service portfolio we're the manufacturer of portable three-phase power quality demand and energy instruments the examples are hdbq family that we're going to talk about today another example is our drain expert the the new product that we've been talking about we also make permanently installed power quality demand and energy instruments so the portable ones are for portability move around easily they're permanently installed they're fixed installed uh in your substations in your switch gear or whatever it is and we also have accompanying analysis software for each product family so our drainview product line our drainview software which we'll be elaborating on today is more intended for our portable products and our pq view and pq view de is more intended for our fixed family of products and our last web meeting um of the fall 2020 we have a tour of pq view and peaky view d e which thurman will be doing i believe that's on december 18th so again please register for that if you haven't done so already uh we also are the us master distributor of our parent companies products we are owned by a company called gauss and metrowatt they make a full line of products precision multimeters and testers electrical safety testers insulation installation and other testers as well as light meters from another sister company called gas and photo and we are the master distributor of uh their entire product line as well uh generally if you see products sold by drainage that are green in color they're they likely come from gossip metrowatt or one of our sister companies uh we do offer free technical support this is actually part of that where we want to make sure you folks have knowledge on the products we're happy to speak to you email call us attend these web meetings uh we want to make sure you're prepared to use the products we want to help you with that but there does come a time where there is paid for training as well where it's beyond the capabilities or the intent of our free technical support um so we certainly do a lot of remote uh training right now certainly in the in the times of covet we do a lot of web meetings under our zoom or whatever the customer's account to help our customers not only help them get to get the products installed properly configured for their application get data out of the products analyze it in the software and know how to use that for their particular application so that is designed around your specific needs whether it be a portable or a fixed product or quite candidly both in a lot of applications this is on-site training that we hope to resume soon but we've taken it remote and that's mostly ken and thurman who do a lot of that our website dranitz.com it's where you registered for this training uh it's not only of course an online product catalog for our products but there are a lot of case studies tech tips and everything else related to our products in the industry so please use that as a resource that's where we house the library of recordings of these sessions so you'll see a lot of educational material on there and a lot of our social media posts and our emails will direct you back to our our website for the collateral material there so uh if you ever want to know the latest information about granite's just log in to our web page where our website our home page is constantly being up to updated in the banners for current information and follow us on your social media platform of choice uh primarily facebook or linkedin uh just a note about tranis uh the products that are designed by dranitz are designed in this very building in edison that we're in right now are also manufactured in our facility here as well um so we're proud to say made in the united states um so things that we design we build okay and we're happy to to and we're proud to to share that so just a uh just some images of the products you can see on the right hand side here this is our portable product line or hdpq and our and our hgbq plus and our sp products which we're going to be focusing on operational training today we have our fairly new drain expert product that we started shipping in october we recently introduced and here's the accompanying drain view software which works with this entire product family we also have our fixed uh family of instruments which is a line of um full-featured pq soft pq instruments for uh high demand applications and very unique things that only the draenei products can provide down to just energy meters and panel meters and they are all pulled together primarily by our pq view or our pq view de software which again we have a training session um in december on that and here you can see an example or some examples of the gossip metrowatt product line multimeters safety testers light meters and these are machine and other types of testers so you can see what i was referring to before with the green color so if you have any more questions about the uh the drainage line of the gossip metro outline just please reach out to us or send us a chat we're happy to answer them so focusing on today's training this is just generic and general training operational training on the hdpq family which really encompasses the plus line again we have our visa our guide our explorer explorer 400 that's available on the plus portable and the sp packages where the the portable package includes the uh the color touch display that you see there the sp package does not have that it's in a remote package but has the benefit of being able to power from the phase that you're measuring so these are 1000 volt instruments however the sp has a little power supply input on the left where you can jumper over and power the instrument from anything you're measuring 600 volts and less so it's a thousand volt instrument but the power supply is only rated at at 600 volts ac and 500 volts dc so that's one of the big differentiating features between the uh the portable package and the the sp package they have the exact same communication so on a portable where you may use the touch screen to set it up and do data analysis and use the communications meaning ethernet or wi-fi if it's available in that model as uh as a secondary form of user interface well that secondary form on the portable becomes the primary user interface on the sp okay but it is the exact same interface and these are the exact same instruments measurement wise so they set up exactly the same what you see is identical and what they measure is identical so when you peel back the the cover they are really the same instruments on the inside so once you know one you absolutely know the other given the differences that we spoke about before so what we're going to focus on today and we're going to break this up between myself thurman and ken and get a little more visual again we're going to do a hardware tour of the instrument that ken's going to do just showing the various interfaces the inputs and we'll go on to a full screen view there so you can see ken do that we're going to just do a general overview of the user interface you know what the general things are that are displayed on there we're going to do a brief overview of real-time meters how to access them which buttons to push to see a scope mode or a text mode or something like that and we're going to spend probably the most of our time on the instrument itself on the monitoring setups uh we'll go through the automatic setups where the instrument sets itself up with just a little basic information from you as the user and then the wizard setup which is that step-by-step process to set it you know set it up for a monitoring application however we're not going to focus on any particular application so it's going to be a fairly high level overview again we're happy to answer any specific questions via the chat but the details to set the instrument up for a particular application will come when we cover those applications such as we did last week and we'll do in two weeks from now and we'll also show you how to start and stop monitoring which is very very easy to do we're gonna give a little brief overview on how to review data on the instrument and thurman will be providing these sections here uh just how to do a timeline uh trends and look at events again we're not going to do that analysis we'll just point and show you where those capabilities are then the next step is how to get data out of the instrument and get it to your computer and then ultimately in drain view and there's two ways to do that one is through a usb jump drive which you use a sneaker net to carry to your tran view computer or you just download it via dranview and it winds up in in your in your drain view computer and magically you're just seeing the data right there once it's arrived and then we're going to continue on i believe ken is going to do this section of a drain view tour how to open data in drain view how to browse data and drain you just a high level tour of drain view itself so so that's really what we're going to cover again let's focus on the chats for any questions and without further ado i think our our first section is the hardware tour so let me just stop sharing and ken's going to is going to stand up and describe the hardware so just give it a second there you go okay hello everyone uh out there this is hpq explorer it's a 1000 volt instrument we got four differential inputs on top for your voltages uh what this allows you to do is do more than just uh delta and y it also gives you some of the other odd inputs you know high leg uh open leg delta we also have four inputs for four different cts you can pick the different cts that you want you know we have a couple different ones talk to us about that later on the left side of the instrument has ethernet port this is hardwire ethernet and also has usb import for getting the data out of it it is not for communications between your uh instrument and your computer it's just to retrieve data out of it the right side has a power switch on it has also an optional gps input if you need some gps you need the accuracy if you internal ntp is not enough for you the gps also the power input it's 12 volts power input the uh back of the instrument has a little built-in easel for it so that you can stand the instrument up also these back here allow you little knobs to dress the wires and take the wires and do everything that you need for it we also have a little camera on the front this will copy whatever's on the screen to your database the center is for a mini report to do a little menu report on into the uh instrument while you're recording and then the question mark right here people always ask me where's the manual i don't have a manual well guess what you hit the little question mark the manual will come up on the screen to the screen that you're on so you always have the manual with you you need help and you can't get access to thurman or myself just press the little question mark and the manual will come up to you with no problem uh it's got a nice little rubber boot on it the protection so it will draw uh survive a four foot drop we've done that many times uh basically that's it okay all right nice job thank you ken uh let me start sharing again and we're gonna just talk about a general overview of the user interface okay um just give me one second here okay uh just as a brief overview of the user interface and i'm sharing this is uh what i'm doing here just to describe this is an instrument that we're going to be using for today's session that's mounted at the service entrance of our building our utility is public service electric and gas pseg and this is a service to our approximately 60 000 square foot building here in edison i've got a lot of instrumentation there we do have an hdbq actually several hdbqs on the service entrance so this is the real-time metering that you see here and thurman's going to actually continue when i'm done and describe you know based upon this particular instrument so we have a vnc app um that's running on our computers here you can do this within dram view itself um so we have a direct communication right to the instrument so if i were in front of that instrument downstairs on the first floor of our building this is exactly what would be seen on the front panel the lcd of the instrument this happens to be an hdbq plus portable however we could just as easily have our sp product there and it would look the same remotely but there would not be an a local lcd interface on the instrument for the sp and what you're going to see here and what thurman's going to describe is 90 the same for a visa a guide an explorer and explorer 400. user interface wise there's very few differences between them and really the difference lies in the options that are in the features that are available that like as an example high speed transients on an explorer you have configurations for that that are not available on the guide because it does not have that capability same thing for wi-fi on the guide is not available on the visa so things like that you'll notice some differences but they are 90 plus percent the same so just as a brief overview and i hope you can see my uh my mouse and you can this is the user interface it's divided into three areas we have mostly a task bar what we call interface at the top and this is basically where you can get your time you can get a battery status know if you're connected um and get the information on your wi-fi maybe you want to get your or your wi-fi your ethernet maybe you want to get your ip address uh we also have a status icon here and you can see that's an icon of the instrument oftentimes if you're working with our tech support and you you think you may have an issue they may ask you for the firmware version of your instrument so you would simply click there and then the firmware information the instrument status would come up and there'd be some information that they'll ask probably on this line over here so just to give a brief description and also when you have a usb drive installed in the instrument you plug it in the side when it's mounted and recognized you will see a an icon of a usb jump drive flash drive show up in here so and then thurman will refer to that before or afterwards so we have the the task area of the instrument which is just for general instrument information we have what we call the working area of most screens which is where the meat potatoes is for the product and for the interface and you can see right here this happens to be the home screen of the instrument which has the monitoring status if monitoring is on and off different different facts about the monitoring as well as real-time meters and then many screens such as this one and what we call the working screens will have information at the bottom of the screen so as an example if i go to a a scope mode here which i just clicked right over here it'll load up in a real-time oscilloscope mode which you can see and then we have soft keys at the bottom so these are the same keys that i'm i'm showing you remotely that you'd be touching on the portable device that you'd be touching remotely as as like what i'm doing for the sp or remote connection to the portable device so again we have the task bar at the top we have working area which is kind of what you're viewing at the time and then soft keys at the bottom that relate directly to what's being displayed in the working area so that's just a general overview of the user interface just what the different components are and now we'll just pass it over to thurman who will talk about the details of of the real time and it'll progress through that thank you ross if you permit me to share i will go ahead and do that yes i have it now and okay thank you ross good morning or our good evening or for i'm so sorry to say good afternoon uh for some of you that are international uh i am thurman bridgers and i'm going to spend some time we're going to talk about the different modes of setup uh using hdpq whether it's the portable or the semi-portable uh the approach is uh identical as far as uh setting the instrument up for a monitoring application uh i i i i sort of cheated a little bit ross uh was on one instrument i actually have logged on to another uh because i want to show you a monitoring setups from scratch i didn't want to interrupt the monitoring that was going on with the instrument that ross was demonstrating so so if the voltage values and amperage values look different that's why we're not exactly on the same instrument so the first approach that i want to take is and this is the most common and i would call it an out of the box type of setup you don't really have to get into a lot of menus and things of that nature and that's all in the instrument design where i can literally take the instrument out of the box connect it to a circuit and run this mode which we call automatic setup which will set up the instrument automatically for a given monitoring scenario it's just a minimal amount of information that you have to tell the instrument or enter into the instrument to complete the monitoring setup and so we're gonna do that now by simply going to uh to start monitoring setup icon here it looks like the play button on a tape recorder or or similar device and if i select it then you see you have your different functions here automatic setup for power quality automatic setup for energy demand again that sort of demonstrates the versatility of this particular product where i can use it for uh virtually any power monitoring application so it's not just power quality it's not just energy of demand it can be both so it's the most versatile instrument on the market as far as monitoring power i like to use power as as opposed to power quality when you say power quality it kind of puts it into this niche of power quality only you may have an application in which you needn't need to do a demand survey or things of that nature and this instrument is equally capable of doing that but having said that work our application here is going to be uh set up for uh power quality and really it's just a couple steps you would select this option what the instrument does now is now it's assuming that you've already made your voltage and current connections to a given circuit the instrument is then going to sense the number of channels that you're using as far as voltage it's going to sense what those values are and then it's going to come back and it's going to say this is what my best guess is as far as the circuit type that we're connected to and you can see in this scenario here we're connected to a y circuit with a nominal voltage of 120 volts uh the comes back with the nominal current but that's the bit of information that you have to add and then it does other things such as the frequency and how much free space you have remaining so the first place that you have an option to let's say edit is the name very often a monitoring session you might want to give it a unique name so you can better organize it later on in post in this case here you put in a unique name the default is hdpq of course you put in unique name the second place in which you would enter information as far as to complete your monitoring setup is the card probes so you would have to tell the instrument the instrument wants to know what current probes are you using so by clicking on the probe or touching if you're local you're you're presented with the current probe selection now there's a couple things to keep in mind here number one uh the instrument does allow you to mix and match you know there's some instrumentation out there that you have to have the same current probe on all the channels this instrument will allow you to mix and match probes which makes it extremely versatile for a lot of different monitoring applications but in this scenario here we're going to go ahead and go to the drop down and in the drop down you have the various different probes that are supported by the instrument as you can see the list is quite extensive even our ac dc probes ross mentioned earlier the instrument's ability to monitor dc voltage and dc current where we monitor dc current using our ac dc probes so i'm going to go ahead and select the most popular probe that we sell is our drain flex probe and so it's a couple things that you see here number one the range the our flexible probes are multi-range probes the benefit there is that i can have one set of probes which i can use for low current medium current and high current applications this particular probe has three different ranges that you would select from so this is what you have to tell the instrument on it probe itself on the integrator it has a range selector switch so you want to make sure that whatever range that you that you have selected on the integrator you want to make sure that it matches well this matches the the selection on your on the integrator so in this case here i'm going to go ahead and select 300 amps and then here as a shortcut i mean you could do it the long way and and do the same function for each of the remaining channels or you can just simply use the shortcut here and it sets them all the same so that's a way to to quickly get through a setup the turns ratio that comes into play where for medium and high voltage applications where the instrument is basically piggyback on existing pt's and cts you know a very common medium voltage application is 4160 for 4.1 kb obviously you can't bring those voltages directly to the instrument as it's rated up to a thousand volts so typically in those applications the instrument is connected to existing pts for the voltage and cts for the current so that's what we mean by piggybacking off existing pt and ct secondaries rule of thumb is is that if your direct connect you know up to a thousand volts uh then these values basically remain at one but in cases where you're going to be piggyback off existing pts and cts you need to know what the ratio of those devices are a typical ratio that you would see in 4160 is 4160 to 120 or it might be 4160 to 60. so that that's a very common ratio a common ratio that you might see for current 3005 2005 a thousand to five those are very common ratios that you would see as far as uh cts are concerned but once you've entered in the uh the correct information then you would go to exit in some cases the exit button also serves as an enter button so in this case here it's serving as the enter button once i click exit then the settings are the settings are saved the instrument comes back does another detection of the circuit and it comes back and gives me uh the values that i'm looking for now this screen here allows you to do some sanity checks and and those sanity checks are making sure the average is what i expect it to be in some cases you might be making a connection before the circuit is energized so that's an exception um but most of the time you're going to be connected in which there is some assemblance of current so obviously when we say sanity checks you want to make sure it's reading the correct voltage values make sure you're reading roughly the correct current values the other thing you have from a graphical perspective you have your built-in scope ross showed you an example of lifetime scope where you get this oscilloscope type display the one thing that you can look for here and one of the most common things that we see uh with particularly relating to the cts or current probes is what we call reverse polarity reverse polarity will show up very easily on on this scope mode where you can see here's your uh this trace here is my current for a here's my current for b current for c if i was inverted polarity inverted on the ct then my current would actually be 180 degrees out so that's how you can use this screen to determine if uh if you have uh reverse cts and of course there's another way as well you can go to you can use the phaser display so if i click on phaser i can see it from a phasor perspective again if we're looking at phase a here which is our voltage vector and our current vector represented by voltage a and i a if i had a reverse ct or verse current probe then this will be 180 degrees out so there's a very easy way of determining uh if you're connected properly so i like to use scope mode i like to use phaser as far as the sanity checks before i walk away from the instrument once my uh meter screen and my either my scope mode or my phasers are all in agreement and i feel comfortable that i'm getting the right readings then again i would hit accept and after going to accept the instrument will initiate the monitoring session and so the monitoring session tells you that it's starting the file name that you may have changed in this in the setup for the uh first piece of information that it was looking for uh and then you're off and monitoring and then you obviously you're gonna leave the instrument there for x period of time it might be a day might be a month might be six months the instrument having four gigabytes of memory you can actually have months worth of storage for a power analyzer data logger harmonic analyzer energy demand recorder it has more memory than any instrument in its class on the market so four gigabytes is a lot of memory now after the instrument has been monitoring for a while you're ready to stop a monitoring session and so you walk up to the instrument you can see that the stop monitoring icon again looks like a stop button on a tape recorder or a similar device a couple rules of thumb while monitoring is on all real-time functions are available so if i wanted to uh to go in and see something like a meter reading and i go to something like text display these values are all available although i should say these functions are all available while monitoring is on so that's a rule of thumb monitoring is on all real-time functions are available and we'll just go ahead and exit out here however viewing of data you can only view data and one of the benefits of having a local display if you kind of want to get a quick snapshot to what you recorded before you go through the post analysis process is using the view data function however the view data function is only valid when monitoring is off okay so now we've we've approached our instrument we're ready to stop our monitoring session we simply go to stop monitoring and then we acknowledge it by stop monitoring now the instrument goes through the stop monitoring process and now monitoring has stopped okay we're going to save the view data analysis after we complete our second option uh of setting up the instrument so we'll leave that for last so now we're you know in which case there are many times in which the automatic setup may not be detailed enough and what i mean by that is may not give you enough flexibility there may be changes that you need to make in the setup for a given application there's a lot of different power monitoring applications out there it might be in rush might be a harmonic study might be just energy and demand in which the automatic setup might be too generic so you need to add you need to customize it well that's where the second mode of setup comes into play in which we call the wizard setup that ross mentioned earlier and so to begin the wizard setup you basically the the approach is still the same if we start setup monitoring you just go to the icon here and then you're presented with this window and then the option that you're going to choose is wizard setup and so going to the wizard setup will allow the our our screen to load here and the wizard setup is going to take you through these steps and these and going through these steps allows you to customize a given monitoring scenario first thing obviously is the probes and the screen or the window is going to be identical as if we were using automatic setup and the approach would be the same you would select your particular current probe for the application if it's a multi-range current probe then you're going to select the range that you're using if your medium and high voltage applications where you piggyback off existing pcs and cts you're going to put in the appropriate ratios once you've completed that then you're ready to move on to the next phase wiring config you can move to the next phase by simply clicking on the tab here or you can just simply hit next whatever your preference is if you go to wiring config the instrument basically gives you some warning messages obviously making sure that you're qualified and that you have all the safety requirements in place because remember a lot of times i would probably say 95 of the time or more you're going to be making connections to a live circuit so obviously you want to make sure that you have all the safety precautions in place when you do that all the ppe and things of that nature so once you acknowledge the message there then it presents you with uh your wiring config now there's a a number of there's several pieces of information here that you get from this screen here that is very useful very beneficial in the monitoring setup number one the instrument will automatically try to go out and sense the circuit type and it'll come back and say i think this is a wide circuit but it might be something different three-phase delta it might be three-phase delta this allows you to kind of override that it might be generic generic is where i can use uh as ken mentioned at the onset uh eight it's an your typical eight channel power monitor analyzer well those eight channels can be used can be combined as four separate channels for voltage and current monitoring for single phase so there's a there's applications in which you may uh where that would be desirable but in this case here you can override it by selecting the appropriate circuit type for the given application the other thing that you have is a reference point so if i'm connected to a delta circuit if my application i should say if my application is a y circuit how do i connect to that circuit you know rather than leasing through a user's guide the diagram is right here is easy to follow you also have your phaser display which tells you how you're actually connected and what the typical connection should be based on the circuit types that's that's another what i call a sanity check issue uh that you can uh use uh also you can go to the scope mode if people are prefer to have real-time waveforms you can use real-time waveforms uh via scope mode the instrument as here will also check as far as making sure that you within a what we say the voltage and current measurement range that will provide the best accuracy so what i mean by that is for example we see it all the time where someone will have use a current probe that might be rated for 3000 amps but they're monitoring an ampere of current well obviously you're under ranging as far as our current probe is concerned now the probe amplitude wise may give may read one amp but your phase accurate is going to be way off and that's going to affect other parameters like your wattage and things of that nature so what the instrument does here to automatically check to make sure that you're within the measurement range and usually your your target is to be somewhere in the middle of the measurement range to have the best accuracy the instrument does this automatically now there are cases in which you're connected to a circuit before it's energized so when that happens you're obviously your currents are not going to be in that ideal range to give you the best accuracy so the instrument is going to come back and it's going to tell you that you have a mismatch these two work hand in hand if i'm under current as far as whatever current probe that i'm using and i have a mismatch then i'm not going to be able to determine the sequence so those two are hand in hand we get those calls quite commonly and usually it's a it's a matter of just under uh the current probe being under range if you know that once the load is energized the currents are going to fall back fall into what we call a sweet spot as you can see it vacillating here then you can proceed on and you do that by hitting next or you go to nominal frequency tab again whatever your preference is so then it loads the next page and a lot of this is fairly straightforward and most of the time for typical type monitoring uh you're going to use whatever is the the default is here uh but they are and we'll we'll talk about those in later sessions uh there are certain applications in which you would need to go in and edit these windows here but in this case here we're just going to proceed on um the sync channel like i said a lot of times there's channel 8 balls there may be instances related to the type of the monitoring application in which you would need to change the sync channel to either channel d volts or even channel a amps so the instrument has the ability to synchronize from a current signal as well then we're going to go to monitoring mode and the monitoring mode these are basically monitoring templates and they're there to take a lot of the work out of setting up an instrument if you didn't have these monitoring templates and you can see each one of these are related to a given type of monitoring scenario if you didn't have these monitoring templating you would pretty much have to set up the instrument from scratch every time you go out and perform a monitoring session so these monitoring templates are merely shortcuts they take a lot of the work out of setting up the instrument for a given application you do have the ability however to go in and edit each of these templates to even fine-tune a particular application so the flexibility is there as well again uh the other sections here are unique to certain types of monitoring scenarios or applications that we'll cover later on ross mentioned that at the onset so typically the user will select a monitoring template and then you're off to the next step the the editing of the monitoring templates that we saw in the previous screen that all takes place in the in this screen here and again we won't get into the detailed stuff at this point but that's how one would go in and edit it any one of the monitoring templates that they've selected in the previous screen so after you've gone in and you've added such uh then you're ready for the uh finalization stage the finalization stage there's a couple things that you have available here number one is viewing a configuration and then saving the configuration this is very beneficial because if there is a unique monitoring application that you perform quite frequently you can actually save that monitoring template and then just simply upload it every time you have that particular monitoring scenario that saves you a lot of work avoid you know customizing a setup every time you encounter that particular monitoring scenario so i can save the configuration uh by giving it a unique name if i go to save here you basically give it a unique name just by typing in the information also you can give the monitoring session a unique name other than the default which is hd http q1 after you've completed the information there you're simply ready to initiate monitoring again by going to start monitoring or next in this case here i'll go ahead and i'll select start monitoring now when you're ready to begin a monitoring session you do have a a couple of options number one if you simply just want to use it as a meter and it'll probably be a very expensive meter and probably not the reason why you would purchase the instrument as a meter but you can use it as a meter or you can use it as uh what you probably purchased it for and that's to basically log and detect power quality events and and things of that nature so i would simply go to accept and now your nana begins the monitoring scenario here you can see gives you all the information is starting loads the configuration and now monitoring is on you can tell by looking at in my opinion what i usually do i look at two things to determine if monitoring is on number one monitoring status is either on or off number two the icon is changed from your typical play button to the stop button so those uh those are things that i look for to determine that monitoring is on and as i said before real time functions are available why monitoring is on view data is not so monitoring would have to be turned off so you've been monitoring for a while and now you're ready to view data get a quick preview get your chances are you're not going to do a detailed analysis of data using the instrument's local display that's what the software is which is included dram view that's what the software does but a lot of times since you have a local display you may want to see a quick preview of data so this is how you would basically do that when monitoring is off again following the rule that monitoring must be off and we go to stop monitoring now the view data function now becomes available and so by going to view data i can basically go to an event list i can see if there was in uh any events recorded you can see here this is a quick snapshot of data from the monitoring sessions that we've done earlier or i can view any trend data now we probably haven't been monitoring long enough to give us any real useful trend data but you would basically have your trends just like if you're viewing a time plot uh you have the ability to view event list any waveform data if you want to go that far as to doing waveform analysis so again and really what i use the local display for and monitoring applications is to kind of give me a snapshot of what i have before i go to the next before i go to post as well as analyzing the data so these are some of the tools that you have there now uh a very common scenario that comes up is that i've been monitoring for a while uh now i'm ready for the next step i've gone in i've done my preview i know i have data there on the instrument i know i have a data file so now the next step is well how do i get that data to the software which is the dram view software for post analysis reporting things of that nature so there's there's basically two ways of getting data from the instrument one and you heard the term early on sneakernet that's basically walking up to the instrument with a thumb drive inserting into the usb port and then going to the appropriate screen which i'm going to show you shortly as far as saving the data to a thumb drive and then basically sneaking that over to your computer running the software plug it in the computer usb port launch the software read the data file okay that's one way the other method is establishing a communication link to the instrument and downloading the data via communication again that lends into the instrument's versatility because there may be occasions where the instrument might be in a remote location somewhere and maybe you have a connection to it via wireless modem or something similar to that and the instrument itself can support wireless modems is almost virtually plug-and-play via the instrument's ethernet port so you can make a connection to the instrument to download data you can make a connection to the instrument for remote setup changes things of that nature but let's look at the first scenario which is archiving the data to a thumb drive once a thumb drive the first thing you want to make sure is that when you insert the thumb drive into the usb port on the instrument and ross mentioned this earlier you want to make sure that the instrument has acknowledged that the thump that it sees the thumb drive and so it does that by giving you the thumb drive symbol in the icon that looks like a computer screen so once we have that acknowledgement it's recognized the thumb drive then we're ready to go to the next step which is navigating to the appropriate screen that will allow us to download the data the other thing i the other point to remember and you do this by going to manage memory when monitoring is on you do not have access to managed memory it'll lock you out so again monitoring has to be off how do i know monitoring is off in this scenario well let's see this icon here it's the play button so if it was the stop button that means monitoring would be still on but since it's a play button i know that monitoring is off and now that gives me access to the managed memory function screen and what you see here and this is some things to note here a monitoring session each one you can see each one is monitoring sessions here you can actually see some new ones that i basically created during our our session here so monitoring session is anytime you initiate monitoring and the instrument stops for whatever reason and it may stop because it may stop because uh you manually stopped it or it may stop because maybe the instrument ran out of battery and then restarted or so anytime it starts and stops it creates a monitoring session which is why you see all the sessions here so it's very important and we see this a lot is that if you're looking for data within a certain range you want to verify that you've downloaded that particular monitoring session if you have a monitoring scenario where maybe you created multiple sessions maybe someone invently turned the instrument off turned it back on you want to make sure that the data that you're looking for is within the range you have your start and you have your end and you have the number of records in a given session so you basically select each one that you want to archive and you use to archive the usb and it'll begin the process of archiving the data if you have a scenario in which you have multiple monitoring sessions for you know for a given monitoring period you can download them individually and you can stitch them together in dram view that's one of the the pc software dram view has a function that will allow you to stitch them together so don't panic if if you have a monitoring scenario and it has more than one session in it you can certainly do that so after you've archived the date of the usb now as i said earlier you go over to the computer and you know running dram view uh you simply use the we're gonna exit out of here you simply use the uh the file open function navigate over to where the thumb drive is and then read in the data files so now the next scenario i'm going to take you through and my final home stretch here is how do i get data via remote connection um well number one in dram view on the ribbon bar on the taskbar you have your download function so you would select the download function when you're setting up a new download session you give it a name the ip address the user and password by default the username is admin and the password is drainits with a capital d so that's the the login credentials once you have uh created the login credentials and you would make a connection to the instrument this probably look looks very similar to if you were viewing the instrument locally you have these very you have all your monitoring sessions here and so you would just basically check off to which monitoring sessions that you want to download okay and again the the key here is making sure that the data that you're looking for falls within these windows here sometimes users will have an instrument that will have monitoring sessions that are very old they forgot to clear the memory or whatever and so it's very important to keep in mind that the data set that i'm looking for i want to make sure it falls within the range of a particular monitoring session and also keep in mind that you may have multiple monitoring sessions for a given monitoring scenario for the reasons that i explained earlier and uh the other option i'll finally end on this if you want it to be more selective say if i selected a monitoring session and i only want to download a certain part of it you can use these drop downs here or you can be more selective only you're looking for an hour's worth or a day's worth so you can use those options okay the next step would be to visualize and analyze the data and i'm going to pass that over to my colleague ken demario he is going to take you through a tour of typical viewing and analyzing of the data so i'm going to stop sharing ken and it should be all yours at this point thank you everyone thank you thurman let me get some data up here i looked at the same data uh same http queues that durham was just looking at i downloaded data for the last two days from our service engines right here when you get a hold of data from the hebq uh as thurman said you downloaded i looked at data from the last two days i just highlighted what i wanted and let me show you exactly what you have to do i just called edison service entrance y admin and the password is dranitz and just told it to download for two days worth of data and it took two minutes three minutes when you look at the data first thing comes up is it shows you the four since this is a y the four voltages if you want to look at voltage and current together just find a empty spot on the graph right click go to properties and bring up the chart properties what i want to look at is the three voltages and the three currents at the same time just highlight what you want and you will get your voltage and your current uh if you notice over here on the left hand side these are events as happened in the last two days and if you notice the little triangle up at the top as you change to different events it's going to show you where you are and show you what happens over here on the right hand side so on the center plot we have our time plot with our data the right is the event detail and we had a little bit of a drop out for you know 1 16 of a cycle right here so that's what will happen back and forth between the two of them if you want to see the high and low you can also insert a table and do statistics and it'll show you the min max and average of the data right then and there there's there are multiple ways we're going to do a full dram view analysis but i just wanted to show you the last two days of data give you a quick overview of dranit's data and that's basically it so i'm going to turn it back to ross right now and you can look at that later on all right thank you ken and thurman good job we appreciate it um so that's a general overview of how um drain view works how the instrument works how the setups work again for the specifics of those you know please focus on the application sessions that we're going to have and we did have last week and we're going to continue next week so we'll give specifics on instruments set up for those particular applications and also on the analysis and as we did with the generator testing from last week so um we're going to open up to questions and if i could just ask the other guys to mute their their audio here please um all right thank you uh we have a couple questions that came in and i'll ask ken and thurm to help with these things first one from patrick since you're not using a current probe on the neutral do you turn off d in the probe tab right yeah we would suggest that you do that there's going to be no harm in leaving it on um since you won't be triggering on it but you can certainly turn that off it's mostly your option but it would be the best way to do things uh melissa asks can we remotely restart or stop monitoring of course yes that's basically what thurman showed um you have the ability to do that um can you please um so you have the ability to fully remote control the instrument everything that you can do on the front panel except for physically turn it off and on uh you have the ability to fully remote control the monitoring the setups and starting and stopping monitoring and that's either through drain view in the vnc or in a separate vnc remote vnc application and again that can that app can be downloaded from the um apple store or the google play store on your smartphone or on your tablet as well so it does not have to be pc based drain view is pc based but these free vnc apps and you want to make sure it's a vnc viewer can be downloaded at no charge from your preferred app store okay um and i think that's it for the questions that we have right now we have another one from melissa yeah this is memory capacity okay why don't you take that through sure i can take it uh yeah right four months is certainly doable uh by default but there is some things to keep in mind uh there's a couple factors number one the sensitivity of thresholds the instrument is report by exception you can basically tell it what's good or what's bad so that in a sense is this sensitivity and then also the activity on a given circuit but typically speaking with four gigabytes of data four months of monitoring would would be plenty especially if you're using it in a data logging mode it's it's more than it's plenty yeah absolutely it's uh you know quite candidly if you've got four gigabytes of pq data over several months you probably have a very severe pq problem or or the instrument isn't connected or isn't uh configured properly so it's more than enough memory um so we have another question from michael um in events what does waveform mean and i'm assuming michael you're referring to when ken was showing you the uh um the the drain view stuff uh waveform would be um would that be a waveform trigger guys yes it would be waveform trigger yeah we spoke about this in the the generator testing last week it's something very unique to dranitz um and that's that cycle by cycle comparison for changes in cycles um and that was key to the generator step load testing that we discussed last week where um it's what it's doing there's there's two different ways to do it and the most common way it divides a waveform up into these little windows as a percent of the 60 hertz cycle and um you compare that same window to that same window in time of the previous cycle and if it changes by the amount that you've programmed that's a wave shape event and uh michael that's what you're seeing as a wave shape event and that's what triggered um that short that short change that that ken showed us earlier um jay asks can you go over how to set up remote monitoring um yeah we could do that real quick yeah i could i could yeah let me take that let's do it and i'm assuming jay you're talking about the communications part of it yeah and so i'll ask thurman to go through just the ip setup and dhcp versus static and it's not a problem so uh let's go back to our previous screen here and uh we'll share it from this aspect here uh i'm going to establish and here's an example of the end result of remote monitoring that was mentioned earlier as far as you know turning off monitoring turning on monitoring here i actually established a and to ross's point vnc the vnc viewer is the component that is used to communicate with our with c in this case hdpq the hp hdpq instrument itself has a built-in vnc server that's actually built into the instrument and so to interface with the vnc server you use the vnc client there's two options one at the roster's point earlier you can go to your web uh your favorite web store and download the vnc client and and and so you have that end of it to communicate with our vse server or more conveniently since drag view is included with all the hdp hdpq packages we sell you can use the vnc client within dram view which is what we're doing here i do this for mainly for convenience so if i'm setting up a remote session to an instrument i would simply go to new and then i will give the the session the name you can see here it uses the default name and then i would enter the ip address and i'll show you later an ip address setup so i would enter the ip address that's been assigned to the instrument now the instrument can basically acquire ip addresses and one or two methods static which we recommend or dynamic which is uh hd hd was dhcp so if the instrument is on a a local area network and you can have it get his ip address from a dhcp server our recommendation usually in remote setups is to have a static ip address assigned to the instrument so in this case you would you would enter the appropriate ip address and once you've done that then you're ready to communicate to connect to it in this case here if i select the session i created previously i go to connect this now i have remote communications to the instrument now one says well how do i set the instrument up for that and so the other the other option is you go to set up communication options so by going to this function here and again i'm doing this remotely but if you're local to the instrument you would just simply you know do it locally on the instrument so here in this setup here you can see i'm using a static ip i'm not using dhcp again the only reason the only way i would use dhcp i should say is you want the instrument to acquire an ip address from a dhcp server that might be on a local area network or wide area network in this case here i have an ips static ip address which i've assigned to the instrument i it comes with the subnet mask and the gateway that's all i need as far as setting up an ip address for the instrument then the other thing here under as i mentioned earlier the instrument has a built-in vnc server well the vnc server as you saw in some examples the username and password here i would define what the first of all to enable the vnc server so in those applications which maybe because of security reasons things of that nature you want to disable the dnc server to keep someone from logging on you can do that if vnc server is enabled then you can give it a unique password the factory default course is granted so once you have that set up now you're ready to communicate to the instrument for remote programming to turn monitoring on and off remotely and of course to download data so i hope that i hope that answers your question okay very good thurman um just if i could add that one of the reasons not to use dhcp in it terms it's a leased ip address and even though you can easily know what the ip address is or was that was assigned by the network in theory it can change so if you turn off that instrument and start it back up again you may have a different ip address just a second thing to add on some of the things that thurman said when you're remotely configuring the instrument be very careful with the ip address because you are by nature already configured for ip communications you've established that connection but if then you go ahead and change that ip address now you've locked yourself out of that instrument you would need to reconnect and it has to be a proper ip address that you enter so um so just little uh words to the y's there just to add to what thurman said um kyle asks if you uh set the monitor's character character mode to all data versus triggering how long can we monitor versus the four with the four gigabytes and i'm assuming what you're saying is just using journal and trends versus the uh the triggers with the pq triggers with wave shapes and that's kind of a difficult question to answer kyle it's uh you can probably go for a year or more a lot of it depends upon how frequently you set those journals those timed intervals at the factory defaults of uh 10 or 15 minutes whatever the particular parameter is it'll it'll record for a year or more we do not specify that because there's so many variables involved but that's just a general rule i i i think if i could just chime in um i think what kyle might be asking if does the characterizer mode dictate how much data gets stored in the instrument the the characterizer mode and the instrument simply if i can put it in layman's terms you know how do i uh present the data for example um you know if i have a a reduction in voltage how do i characterize that is it a sag if it's an increase in voltage how do i characterize that it's a swell if i have a a what we call a spike or you might call a transient event how do i characterize that do i characterize it as a multi-cycle transient things of that nature so uh there's one thing is the what determines how much data gets stored by the instrument is the instrument setup again how tolerant or how sensitive you make the instrument to recording data to roster's point your journal intervals and things of that nature that determines how much data the instrument will collect the characterizing mode basically uh tells you how to characterize the data what it means putting it in in simple to understand terms so i i hope that uh hope that answers your question that's good thurman thank you uh tony asks will you go over aren't viewing rms instantaneous or harmonic data not at this session tony um we're going to actually focus on that in two weeks when we get back to our application training we're actually focused on ieee 519 2014 harmonix and we can certainly address that but just to briefly answer your question you have the ability in drag view and certainly in the instrument itself but it's easier to do in drag view of viewing any any voltage channel any current channel viewing the voltage of the current or individual harmonics that may have been recorded by the instrument or the vthd and i thd but we will definitely be elaborating on that um in our next session when we cover the ieee 519 harmonics because it directly relates um excuse me kevin asked if i set up the meter for energy monitoring can i still access pq data in drainview the answer is maybe because it depends upon what you're recording in general energy is not pq if you need pq you need to enable the pq capabilities but there there is overlap such as thd and things like that but you're you're not going to get the sags or the dips or the swells or the transients and the wave shapes associated with them but you will get a minimal amount of pq data in there so if you the recommendation would be if you want pq even though your focus is energy well we have the ability to do that it's a unique capability of the the dranitz products it's kind of an a la carte setting where you can enable what's important for your application so you can go to a monitoring mode that'll record a default set of parameters and you can add to that for your particular application i would also add to that is that if you set up the instrument for just using one of the monitoring templates that i talked about earlier uh the most common monitoring template that's used when someone's going through the widget setup is the first one which is standard power quality i believe is ieee if you use that monitoring template it's it's focused to power quality but it's also going to provide you with energy monitoring as well so just to add on to that very good thurman thank you and then jay also asked can you use any ip number the answer is absolutely no it has to be a an ip address that's valid for the network that you're configured as an example if i'm going to plug into my local network here i have to know what the valid ip address is for your network if you're unfamiliar with that i suggest you speak to your i.t person or contact ken or thurman or myself and tech support to help out because it is that you know these are not dranit's rules these are networking rules um with the ip stacks so there's certain ranges of addresses that are valid not only to just enter period in ip network but that will function on your network so uh however when you're directly connected from a computer to hdpq as long as they're on the same network and you've configured both to do that it's kind of random which ip address you will choose to assign to each of those the instrument or the uh the pc within the range of valid addresses that you choose so a little bit complex but um you know ask us for more help and then kevin asks excuse me uh how is remote config done different with wi-fi uh if you're talking about remote config of the instrument as what thurman demonstrated it's exactly the same once you're up on a wi-fi network the connection to a wi-fi network's a little bit different than just a regular ethernet because you have to find your hotspot that your or your router that you're connected to make that connection and enter in any security that's compatible once you establish that connection it's absolutely exactly the same as you're doing with an ethernet cable the instrument doesn't know the difference you don't know the difference once you're connected uh melissa asks uh what are the expected reasons for monitoring to stop unwillingly temperature below certain degrees fahrenheit or whatever how long is the life better a battery life for continuous monitoring um when there's really no normal reason to stop other than maybe memory filled something like that that it's programmed to do but there can be exception situations where um the battery or the instrument loses power as you're alluding to here and the battery depletes and in those situations the uh it'll restore monitoring once it is back energized it gets mains power back uh the battery life is about um two and a half to three hours depending upon the model let's say two to three hours depending upon the model where the explorers are don't have quite it's about two two and a half hours the v's in the guide is about two and a half to three hours battery and that's because the um the explorer has high speed transients in it it's additional circuitry additional loading on the battery but to answer your question it's when something happens the instrument may have a fault or something it reboots itself uh or usually the instrument lost power and the battery depleted those are the reasons to uh unwillingly in your turn stop stop monitoring and then john asks is there any problem with leaving the charger connected during monitoring absolutely not we recommend that you do that um that is uh that keeps the battery charged and i'm assuming that it's more than just a few minutes uh that you're recording but certainly um that's what keeps the battery charged the batteries uh ups for your uh for your monitoring application so we would recommend that you do that um i think that's it for the question so uh you know we'll be here for a little bit of time uh you know please chat up any additional questions we certainly appreciate your time today uh again our next session we're skipping next week due to our thanksgiving in the united states our next session will be on december 2nd and we're going to cover the ieee 519 2014 um vfd and dc monitoring applications and the setup and the specifics for those so uh thank you very much happy thanksgiving to everyone here in the united states stay safe and we'll we hope to see you on the second
