Some help with a circuit I'm working on...hopefully

Hey Mark,
After reading the pages that you pointed out more in depth, I digress. They do seem to be using a current transformer to sense voltage...Which is very weird, in and of itself because plasma machines are constant current devices. I would love for one of the circuit gurus on this board educate me further on this scheme. It sure has me scratching my head All of the other THC's out there do it with a scaler (divider)... Oh boy, I'm baffled now!
Thanks Mark,
Chris

It's beyond my knowledge. You may want to ask over on the cnczone forum. Someone can probably tell you if this method works?
