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.

If I have a motor of 1 MW with 6.6 kV, running at 35% load, how can I save energy without reducing the load?

Why we transmit the power at the voltage in the multiple of 11 or 1.1 like 11kv, 22kv, 66kv, 132kv...... some one told me that it is due to fomr factor 1.1 of sine wave. its fine but while transforming we can choose any voltage, so why only multiple of 1.1 there also.......? plz tell me.
