Used a 37.5 kva version ( 125 kvdc, about 90 kvac,270 mA with the diodes
removed) of this on one (full core, so still weighed 120 lbs without oil).
The problem with these is that they are only meant for like 1% duty cycle at
full rating (unlike pole pigs the stock rating is pretty much the absolute
max rating before the core saturates). I run mine at 24 kva (as much as i
can draw before the neighborhood browns out) for 10 min and it gets quite
warm with 5 gal oil and a car engine radiator with a pump and a fan. The cap
is a MMC with CD 943c's (5 strings of 100, expensive even though i caught
them for 1.10 each last year (don't know why they're ~2.50 now) which
explains why x-ray-transformers usually aren't used for TC's even though i
got 20% more spark than with 14.4 kv (higher surge impedence/slower current
rise and lower gap current/I2R losses I'm assuming). Overall, if you can
afford it these make decent TC transformers for short runs as long as you
give them time to cool off afterwords.
