Re: 270V to 13.8kV, 6.5MVA transformer :))

Good grief, if you need that much power seems like it would be easier to get a giant ballast (prob substation line reactor, usually cheaper than equiv. power tranmsformers, especially used, or get a few pigs and parrallel/series the secondaries) and hook up your TC/jacob's ladder directly to the power lines (assuming you could get a 35kV-class rated meter to keep the power co. and law enforcement happy). That way no need to step it down with dozens of 1000MCM cables and back up again. Of course building and running that 6500 kVA TC is a whole other beast. Heck the arcs would be big enuff with just a jacobs ladder, prob way over 150' assuming it wasn't windy. Finding electrodes that wouldn't melt/erode with 34.5kV and 188A+ (or worse, 14.4kV and 451A+) would be a chore tho. Hmmm, maybe if you did the above with 345 kV transmission lines instead, only 18.8A then. Darn, I need to win the lottery or ask Bill Gates for some of his $47B.

You don't often see these voltages and this much power
in a single transformer, so act now:

After you pick it up, call your local power utility
and tell them you want 24000-Amp service (or the
closest they can come to it).

Pricing seems a little steep for a 35-year-old
transformer, though.  Darn.  Guess it won't be mine
:((
