Answer / bibek
in dc supply there is no rate of change of current... so induction is zero.. bt transformer is works on the principle of induction.. as there is no induction the o/p is zero..

Answer / sethu ramanj
1. There is no rate of change of current.
2. When we supply dc current to a inductor,the inductor just
act as a resistor. Due to low resistance of inductor more
current will flow through it and it will damage the inductor
coil and power devices.
if i am wrong plz correct me!!

Grounding. Dear all at one of my site we checked the amps at the earthing cable to the alternator it was found 125 to 130 A. at the neutal cable in same machine found 146A. in the same plant checked the earthing current on other alternator it was 52A, and neutral 116 A. we are facing problems with our controller and the card was damaged once. can that neutral/GND current be a reason? as there is common grounding for the Alternator,Brkr panel,Transformer?
