Could anyone recommend a good transformer oil, other than erm.. transformer oil. i.e. how does vegetable oil behave under 12KV? and temperatures.

Thanks

Chris

Hi All,

HV inductor 6 x 10H 100ma (need to submerse in oil to keep cool and protect insulation)

PSU cap 1.3uf
Pulse cap 20nf

Seems to work ok, the arc quenching is quite bad and I need a de-quing diode.

Got my pri and sec wound, all set to go. I suppose I should really think about putting all my stuff in a nice box with a fan, before it all gets fired by a 500KV spark!

Thanks

Chris

Chris,
I looked at your schematic and I would like to know the values of the components you are using, caps, diodes, and inductors. Can you provide this information? Also, I read your other post. Do you have 2 MOT's? If so, why wouldn't you go ahead and use your first design? Wouldn't it be much more robust than the single MOT design? Regards.
Paul
Think Positive

As it turns out, I don't need two transformers, I can simply reverse the
diodes on the lower half of the circuit.  Effectively its a 4 stage
multiplier but centre tapped and supplied by two diode capacitor circuits,
one for the positive rail and one for the negative rail.

Works quite nicely, I have just managed to vaporise a 10W 10K ohm ceramic
resistor, by taping in on to the end of a nylon pole I put it between the
terminals and the poor resistor exploded (amazing!!!).

Next for the chokes and finally the high voltage pulse capacitor,  I dread
to think what that would do to a 10K ohm resistor.

Thanks

Chris
