  1. TRANSFORMER Breather Conservator Tank Low Voltage Bushes Main Tank Tank Cover Cooling Tubes Drain Off Transformer Circuit Globe


  2. ELECTRICAL ASPECTS OF TRANSFORMER By- MANISH KUMAR SHAKYA


  3. ABOUT ME B.TECH WITH ELECTRICAL AND ELECTRONICS FROM KIET,GHAZIABAD IN 2012 CLEARED GATE,SBI AND IBPS BY- MANISH KUMAR SHAKYA EMAIL ID- mani.shakya5@gmail.com FOLLOW ON https://unacademy.com/user/manish shakya-4406


  4. TARGET AUDIENCE B.tech students of electrical branch Students who are preparing for gate Students who are preparing for engineering services examination Students who are preparing for various psu's Students who are preparing for RRB JE exam


  5. COURSE OVERVIEW INTRODUCTION EMF EQUATION OF TRANSFORMER ELECTRICAL ASPECTS OF TRANSFORMER IMPEDANCE TRANSFORM PROPERTY NO LOAD TEST AND SHORT CIRCUIT TEST


  6. ELECTRICAL ASPECTS Of TRANSFORMER- DEAL TRANSFORMER:-- THE WINDINS RESISTAANCE ARE NEGLIGIBLE Np TO THE CORE RE AND LINK SEcoNDAR)y WINDIN WINDIN * CoRe Loss ARe AssumED TO Be NEGLIGIsLe PEARMERBIury Of THE CORE ls INFINITE ne14=001 HEREFORE THE EXCITING CURRENT ReQUIRED TOCsTABLISH


  7. REQUIRED To ESTASLIsH THe FLwx IN THE CORE Is ZeRo. Coo LINS Of TRANSFORMER-THE CoRE Losses ,H THE CoRe OF TRANSFOR ER ARE DIssIPATED IN THE foRm oe HEAT. TALS HEAT Is PRoDU ED CAN DAMAGE THE INSULATION OR CHAN E TME PERMEAG ILITy of THE CORE AND RESISTANCE IN THE WINDING So We NEED COOLIN METHODS To REDUCE THLS HEAT, THAT ARE ExPLAINED beLow- LN DOOR-TRANSFORMER BELOW 200 KVALKiPo YbH Ampere CAN BE DIRECTLy CooLED By THE NATURAL FloW 0 URROUNDINS AI. So e By CoNvECTION.


  8. LARSE TRANSFORMER CAN BE BUILT IN SAME WAY TAN BUT foRcED CIRCULATIoN OF CLEAN Must Be PRovIDED * DisTRIOUTION TRANSFORMER Below 200 kVA ARe USUAy EMERGED AND ENCLOSED IN A STEEL TANK. X OuL s UseD BecoZ IT s BETTER INSULATOR THAN WATER AND AR ALso As THE POWER RATING INCREASES ExTERNAL RADIATORS ARE ADDED To INCREASE THe CoOLING SURFAcE OF THE OIL FLLED TANK. fOR STILL HIGHER RATING COOLING AAN BLOW AIR Oe THE .RADIATOR.


  9. 2oo4 THE EQUIVALENT CIRCUIT OF THE TRANSFORMER HAS LeAkage REALTANCE AND MAGNETSINS REACTANCe X THEIR MAGNITUDE MAGNIFIES EXPLANATION-WE WANT Excl aTAtt ON CURRENT T6 B MINIMUM. So, Xm sH ouLD HAvE HIGH NALUE AND ule WANT TS TO BE MAXI MU M . So, X12X2 SHOULD HAVE Low VALUE So THey ARE APPRoxIMATELy SAmE VaLvE.
