Re: LTR Pig Project - Long Post!

I see Kevin's page at:
His arc pictures imply that he is running significant power! :-)
I note he mentions 110 Amp at 300 volts into the transformer which is 33kVA.
I guess to really say much about this coil I would need a lot more data on it.
The RMS current through a given cap size and a givin constant firing
voltage is directly proportional to the break rate. Obviously, if other
parameters change with the break rate, then all bets are off. :-)
