Re: [TCML] pole pig ballasting

Thanks for helping me figure this one out Mr. Holmes.  I talked to the
electrician here were I got the transformer and he said it was 1 out of 3
for 3 phase 480v service, and that the supply line is 12470v.  So yes it is
a 12470v primary.  I solved this problem by obtaining a 240in/480out tranny
rated 10kva.  I could just hook that up after the variac and before the pig
and I should get my 12470 out right?  Thanks in advance and thanks to
everyone who has made great suggestions.
