Jay,
Aside from the three phase issue, I assume that you would be planning to
feed 120 or 240 VAC into the 36 volt windings in an attempt to get a
higher voltage (~2,300 VAC) out of the original 440 VAC terminals.
I would not expect the transformer to last very long in this mode of
operation, because the windings would not be insulated to handle such a
high voltage. Furthermore, 2,300 volts is not a particularly high
voltage to run a TC with. You can get nearly the same voltage out of an
ordinary microwave oven transformer that was designed to handle such a
voltage comfortably for extended periods.
Two such MOTs connected together in series at their usually grounded
cores would give you ~4,000 volts, but even that is rather low for TC
use, unless you are going for a DC resonant charging system.

So, I have this huge 3 phase transformer that was slated to step down 480 to 36V at 600 or so amps.
My lack of 3 phase power has led me to wonder if I could use the transformer as a single phase input output via keeping/using only one set of the windings.
Has anyone used a 3 phase transformer as a single phase unit via isolating the unused coils and simply running just the middle leg?
Cheers, Jay
