This question has probably been asked before, I want to connect the high
voltage output of a small like 600 watt MOT I have to the 120 side of a
really large MOT like 1000w to get about 20-30KV out, I'll vacuum pot the
MOTs in oil and cut the center ground on the large MOT to prevent arcing,
does anyone see a problem with this? Will I have to use some sort of
current limiting even tho I'm using a little 600 watt MOT for the primary
YOu've got a lot of problems with doing this...
Typical MOT is 120V in 2400V out (or thereabouts).. so it has a 20:1
Cascading them would, in a perfect world, give you 20*2400 V out (48kV)..
You'll never get that, not because of breakdown, but because the primary of
the second transformer will be horribly saturated by putting 2400V on it.
I doubt you could put 150V into a MOT without encountering saturation.
If you're going to the trouble of potting or oil immersion, why not hook
primaries in parallel and secondaries in series. Many people have run 4 in
series to get 8-10 kV out. Some have even run 6 in series.
