working principle of a transformer | 3 phase transformer's working system | Transformer

hi hope you have seen this Transformer sometimes  it could be a small or big size a Transformer   is a passive electrical device that transfers  electrical voltage levels from one circuit to   another through the process of electromagnetic  induction it is mostly used to increase the   voltage levels between circuits which are called  Step Up or decrease the voltage which is called   Step Down Transformer today this video going to  explain the working function of the Transformer   let's start with the main parts of the Transformer  the core is the main part and it is called the   heart of the Transformer the core is made up of  iron or silicon steel or ferromagnetic materials   it is thin metal strips and lamination  insulated by a coat of varnishes or papers   the core of the three-phase Transformer  consists of three limbs in the same plane   and each limb carries both low voltage  LV winding and high voltage HV winding   the chorus provides a magnetic  path flux around the core the first winding is also known as a coil when it  is supplied by an alternating electrical source   the alternating current through the winding  produces a continually changing and alternating   flux surrounding it if another winding is brought  close to the first winding some portion of this   alternating flux will link with the second winding  as this flux is continually changing the amplitude   and Direction there must be a changing flux  linkage in the secondary winding or coil according   to Faraday's law of electromagnetic induction  there will be an EMF induced in the second   winding if the circuit of this secondary winding  is closed then a current will flow through it   this is the basic working principle of  a transformer the winding which receives   electrical power from the source is known as  the primary winding the winding which gives the   desired output voltage due to Mutual induction  is commonly known as the secondary winding   here if the number of secondary coil turns is  greater than the number of turns primary coils   N1 then it is called a Step up Transformer that  means increasing voltage between the primary to   secondary windings conversely a Transformer  that decreases voltage between the primary to   secondary windings as a step-down Transformer the  alternating current through the primary winding of   each phase produces a continually changing  magnetic field that surrounds the winding   here this magnetic field is linked with the  secondary winding by magnetic flux which flows   through the Transformer core EMF will be produced  at the secondary winding based on Faraday's law   and this induced EMF is defined as mutually  developed EMF insulation is needed between   the primary and secondary winding to prevent  short circuits finally to receive electric   energy from the Transformer insulated  bushings are needed during its working or   transferring the power from the primary to the  secondary winding various energy losses happen   like Eddie's current losses hysteresis losses and  copper losses all these losses generated heat to   prevent heat Transformer oil is used inside the  tank the main role of Transformer oil is to act   as a coolant and to insulate Transformer oil is  an exceptional heat conductor and can effectively   reduce the copper coil's temperature stopping  them from burning not only that externally cooling   tubes or radiators are there the radiator  of the Transformer accelerates the cooling   rate thus it plays a key role to increase the  loading capacity of an electrical Transformer a buckholtz relay is used to detach any fault  inside the Transformer hope you understand the   working function of the Transformer thank  you let's grow up never stop learning foreign
