The Basic Engineering FEED required for proper installation
is to follow the required details of the code that is
required. Engineers find it difficult to do this because
few have been taught the laws of engineering with respect
to Electrical and Detail Engineering. The rules such

As the starting of a dc motor and syn.motor and induction
motor high current flowing through the winding cause the
voltage to reverse polarity. this can cause the windings to
burn out. To avoid this different types of starters are
used. But incase of transformer what Will be used. At
starting no emf is induced in the primary winding.



1. If we apply dc supply to the primary winding of
transformer it will be burnt out. similarly dc supply is
given to field winding of syn. motor and armature winding
of dc motor, they are safe. Remember both windings are
inductive in nature.

What is meant by transformer, why it should be used, with out that equipment what happens if we transformed the supply?

current transformer balance the power level on both sides. e.g in case of step up, at secondary side voltage rise but current decrease and vice versa in case of step down transformer. but how this power level remains same in case of current transformer and voltage transformer
