TYPES OF TRANSFORMERS: • AIR CORE • OPEN CORE • CLOSED CORE • SHELL TYPE
TRANSFORMERS • STEP-UP---- V I • STEP-DOWN---V I
TRANSFORMER LOSSES • COPPER LOSS ( I2R) • HYSTERESIS LOSS • EDDY CURRENT LOSS
REDUCING COPPER LOSS HIGH VOLTAGE
HYSTERESIS LOSS MAGNETIC LAG MINIMIZED BY USING SILICON IRON
AUTOTRANSFORMER SELF-INDUCTION
AUTOTRANSFORMER PRIMARY OF STEP-UP
TRANSFORMER LAW Vs = Ns Vp Np
% EFFICIENCY OF THE TRANSFORMER %EFFICIENCY = Pout. /Pinp. x 100%
