The power of a pole pig is horrendous. No single fixed gap can really
effectively handle the power disappation, even an air blast job. I am sure
that quenching was the issue in both cases. The break rate on a fixed
single gap is set by the de-ionization time of the gas in the arc plus the
instantaneous value of the AC sine wave voltage into the capacitor. With a
flaming arc, you probably were down to only one pulse per half cycle. After
a certain point, all the excess energy supplied by the big Xfrmer went into
the arc and the disappated heat just kept the arc on. Many single series
gaps would have helped a bit, but at power levels in excess of 4-5 KW a
rotary of some sort is a must, preferably with adjustable speed.
Good luck on your system as it is developed.
