Re: Russian high-voltage installation (being scrapped?)



Original poster: Ed Phillips <evp@xxxxxxxxxxx>

"Easy to stack.. I built a "giant NST".. Those transformers have 3
windings.
117 V, 4.5kV, and a 600V winding (designed to connect to a 10 uF, 660VAC
run
cap for PFC).  I feed the bottom transformer with 117 V, and connect the
600V winding to the 600 V winding of the next transformer. Secondaries
in
series.  Two stacks, with a common point grounded makes a 20kV, 450ma
(or
225mA)  current limited transformer.  I mounted the "high" transformers
on
4" standoffs, and connected to core to the 600V winding and one of the
terminals of the 4500V winding, figuring that would reduce the stress. I
also left the capacitor in, figuring PFC is a "good thing"."

	Giant indeed! What have you done with it?
