Some items are into my possession and need to know the specs and what are they. First is this capacitor. First time i see capacitor with 4 connections.On the big pair is written H1, H2 and on the small pair is written L1, L2 I tried to find information online but with no result. My questions are 1)is this a pulse capacitor ? 2)Is this 2 capacitors in one ? One pair of connection (the smal) is 80kv 00.1mf and the other (the big) is 100kv 00.1mf ? 3)Can this type used for AC assuming the voltage is lower from the spec ?

It might also be two 0.01uF 80kv capacitors with a 100kv surge rating. I'm not sure if it is a pulse discharge capacitor but it certainly has the look of one. have you tried looking up that 9 digit code at the bottom?

2 pulse capacitors I have use a large insulator for the positive connection and a small insulator for the negative, so I'd guess that on your capacitor the large insulators are the positives the the small middle connections are for the negatives. I agree with Forty that they are probably both 80kV, with a 100kV surge rating. Not sure how it would go on AC, but if you at least halved the input voltage I don't think it would harm it.

Yeah, connect 5 and 6 to the core. Both these wires need to be grounded to the core at all times when you're using the transformer, otherwise you could risk an arcover between the inner turns of one of the secondaries and the core, which would most likely ruin the transformer.

this transformer has two outputs 180 deg out of phase 1,2. 5,6 are a single turn wire for current mesurement? 7 is electrostatic shield and 3,4 is the primary.
