Hello,
In a pig based system,there is a saftey gap across the transformer
correct? Does one need a gap across the primary tank capacitor ? One
across transformer and one across cap or just one gap across
transformer.( I know its dumb question)

Jeffery,
On my pig powered system, I have a safety gap between the pig and the coil,
across the H.V. feed lines. I use an async rotary gap. I originally did not
have a safety gap across the primary tank capacitor and lost two expensive
commercial caps before I realized I had a 60 hz resonance problem with the
primary ballast and was way over-volting the caps. I now have a safety gap
across the caps but plan to move it to the rotary gap next time I work on it.
When the safety gap mounted directly across the cap fires, it scares the
hell out of me - sounds like a shotgun - and is not good for the caps. Much
better to put it across the rotary so when it fires it does so through the
primary.
