Rotary phase converters or "phase masters" as they
are sometimes refered to as, are widely used in the
broadcast market.
if the transmitter site can only be wired for 1 phase
220
because three phase does not run in the area (usually
very remote)
then a rotary or inverter phase converter is used.
these can supply power in the three digit Kva's.
i would avoid the inverter type as they are more
pricey
and suck alot of juice.
goto
www.broadcast.net and find the listserves.
from there join "radio tech" and
"broadcast" and
ask your question about phase converters there.
a couble weeks ago, a station was selling one they no
longer
needed, don't remember the price but have seen them go
for prices in the hundred's to the thousdands.

I'd appreciate hearing from anyone who has actual
real experience with or knowledge about this.
Whatever size of converter you figure you need, even
with safety
factor,
slop, and such...get the next size up.
