Answer Posted / subhas momdal
At the time of switching of a transformer total flux =
transient flux +steady state flux And it is equal to
double the normal flux. As flux is increase two times the
normal, therefore x-mer core will be run dip into
saturation.hence therefore magnetising current taken from
the supply will be too large nearly 50 times of original.
It is known as inrush current of x-mer.

WE know that for Inductor X=2pifL,In DC f=0,then X=0 so,V=IX=0;But In the DC excitation of rotor of AC generator,DC motor field coil which coils are inductor so why does not applying DC voltage short the rotor coil of AC generator and field coil of motor?If it would then DC source might be damaged but it is not happened.
