Hello all,

The following questiions are directed toward Bart Anderson BUT I will 
appreciate any and all feedback.  Thanks.

I have recently purchased a 15KVA pole pig and am researching the 
control system for it.  I have a 230 amp adjustable arc welder that I 
plan on using for a series ballast and am getting a variac stack for 
the voltage control.  I am looking for an EMI protection circuit and 
saw what looks to be a large EMI filter in the control cabinet of 
Bart's 10KVA "The Gate Keeper" Tesla coil 
(<http://www.classictesla.com/photos/tgk/15.jpg>http://www.classictesla.com/photos/tgk/15.jpg). 
Bart, does what you have work and if so, what are the specs for it... 
and what type of EMI filter would you suggest that I use in a control 
system for a 15KVA pole pig?

Here is a link to the information plate on my pig:

I am looking forward to all replies and will greatly appreciate all 
of the feedback that I receive.

Sincerely, Hal in Tucson

P.S.  Just so you know that I have some experience, I have recently 
completed and fired my first Tesla coil.   It has a 4" secondary, 
runs on a 15KV @ 120mA power system and, as of July 5, throws 4' 
streamers regularly
