I found this cap at work. I'm looking for a spark gap tank cap. It will be a pole pig system using approximately 10kva. Do you think this cap is suitable? The only info I have on it is that it measures 100nf. I assume it must be pretty high voltage considering the size of the insulators. Can you guys help me?
Edit: It weighs 14 lbs. There are no markings on whatsoever.
Do you think its a filter cap or a pulse discharge. I'm guessing pulse.

I've seen a few of these capacitors... I believe if you check the bottom of the can you will likely see a serial number or a stamp. I've seem similar caps being pulled Chinese made - laser and high voltage high current discharge scientific equipment. Most of these caps ran 25 -30 kV DC range -

I know this may not be much help, but if running at 14.4kv with a pig, that is 10.368 Joules per bang if the cap has long enough to charge to full voltage. Does it look like it could take that at 120 or 240bps? I don't know, just saying so that maybe someone with more experience with capacitors can figure something out :P.
Judging by those rods, it just might be pulse. If it is pulse, that is one nice cap!

I wouldn't push that cap over 10KVAC let alone over 1KVA. I think that guy is gonna fail spectacularly. It may be a pulse cap, but without specs. you're playing at your own risk.

Very valid point. I say put it in something to contain any explosion that may take place, or just make a wall with bricks. If it explodes, you sure don't want to be in the way of it!
