Thanks for responding--I have a complete contoller system with 30amp variac, fuses, gauges, Ballast Inductor, etc. My previous experience is three years with NST', one and two at a time, rolled caps, and mmc's that work great. My newest coil is a Magnifier system, which I had been powering with several NST', however I got my hands on this pole pig and wnat to use it, for the obvious reasons.
I hope that gives you a better idea of where I'm at.
I am using a standard 240v in from my main service, one side running through variac and inductor and the other side pretty much straight through to the pig. The powerstat variac only hooks up to contol the voltage of one side, however, according to the volt meter that is tied in after the variac and inductor, it comes up to the correct amount of volts before it hooks up to the pig.
I totally understand the danger involved with these transformers--I'm not a kid(52 in may '04)and I my job requires servicing the lighting system of the store that I work at(very large store), so I'm very careful and have the greatest respect for electricity!
Hope you can help me figure this out. Jeff

: Help-
: If I'm hooking up two 120v lines to my pig, they should be each

: Hi Jeffrey,
: NO - that's not correct. You normally do not use the center lug. However, I
: need a bit more clarification of exactly what you have for power coming
: into the pig before I can answer your questions.
: First: Are you using some type of current limiting ballast that will limit
: your short circuit current to 55-60 amps and a heavy duty relay/cut-off
: switch of some kind?
: Second: Are you attempting to operate the pig off of a single 120 volt
: circuit (hot and neutral) or from a standard 240 volt circuit made up of
: two 120 volt lines (versus neutral), each line phased 180 degrees from each
: other? Or are you trying to drive it off two independent 120 volt branch
: circuits?
: Third: Do you have a variac to control the voltage output?
: The tap setting usually for minor voltage changes and it's position should
: not be relevant to the proper operation of the pig.
: I assume you have had some prior HV experience such as working with NST's
: before tackling this. Be very careful - you will not get a second chance if
: you have a HV accident with this transformer.
