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...
