RE: maxwell pulse cap.

It is a whopper, .075/40kV (tested at 45kV, and it is closer to 81nf than 75) as of right now, I am only using it with 8kV so it is no problem, but I am looking for a pig or PT, which will give me 14.4kV which still doesn't seem that bad, half of 40 is 20. Does anybody know where I can get some of that silicone based oil Dr. R mentioned to refill it with, it still seems Ok, but I really don't want it to die (it is really hard to make a capacitor with 80nf).

Hi Scott,

Which Maxwell is it? If it is the .03/35Kv we often see, it is rated for 50%
voltage reversal which means if you are up in the 12-15kv range, 2 should be
in series as the peaks are ~17K (on the line) and ~21k respectively.
Submerging seems like good idea to me as it will help keep the heat down and
the lost oil from being displaced by air or other contaminates. Someone
please correct if I'm off here.

Everybody,
     I have a maxwell pulse capacitor, which I use for my 6-in
coil.  It seems to work just fine, but I have noticed that it leaks a
small amount of oil (just a tiny bit, barely noticeable).  Is this
really bad, or perfectly normal?  Should I place the capacitor in a
bath of oil to prevent further leakage?  Thanks.
