I have a question about ground current. I have 25 KVA pig, line neutral 
is connected to the case and the case is connected to ground. Last night 
I pulled out my handy meter and checked for current to ground. I found 
that I had a 3 amp current in the ground lead. I turned off the power to 
the pig and checked again, 3 amps ! I turned off the power at the mains 
still 3 amps. Next I checked to see what the voltage was. It wasn't 
measurable < 1 volt. Can anyone tell me what is going on ? Also there is 
no sign of a spark between the ground lead and the ground terminal.
