Re: Large transformer available

Well, I guessing that prob at least 50-100 MVA (prob at least 277/480 low side tho not likely at that size, more like 7200). I'd like to see a spark gap that can handle 1000-2000 amps charging current and multi-kJ caps for more than a few seconds (probably massive and storing MJ's of kinetic energy itself). If I had Bill Gates cash and had the available power (own personal power plant since I don't know if there's such a thing as a 100 MW portable generator and synching mulitple 2 MW ones would be a pain) I'd just use a 437kV (765kV phase to phase) transmission type and use a much smaller cap (tho not physically smaller). Prob cost alot more, but if you have millions to throw at it, why not? Alot less I2R loss. I think DC resonant would be a must unless you had 3 caps and 3 rotaries on same shaft 120deg apart from each other. Ok I'll quit dreaming/drooling now.

I was reading the Mostly Cajun blog (he is an industrial electrician)
and ran into this post:

34.5kV Substation transformer just shy of 50 tons (98,800 pounds weight)

Now __that__ would make a nice large coil...
