Thanks Doc and everyone else who responded. As always your input is 
appreciated. If I find out this guy in Tenn. has a transformer i can 
use I'll probably get it from him since he's really close to home. If 
not though i'll probably try to set up a meeting with your antique 
dealer/ pole pig delivery man. I'll almost definitely need some more 
of your MMC caps. which leads me to another question. If I were to 
run a 10 or 15 KVA pig at full power what is the least amount of your 
caps I would be able to run in parallel without burning them up?

We have 10 kVA pole xmfrs that run on 220 VAC, not 440 VAC. Some of
the large industrial units usually in large quarries, chemical plans,
industrial metal working plants, etc, do actually run on 440 VAC. If
you only have 220 VAC at your home, do not use this type of xmfr.

I have the correct xmfr you need, a standard 220 vac to 14.4 kV 10
kVA pole xmfr.

As with any pole xmfr, a series 220 vac primary current reactor is
required to keep the maximum current from exceeding the value your
capacitor bank requires. With a typical setup, a .05 to .08 uF cap
bank requires 30 to 50 Amps on the 220 volt side. Your series power
reactor must limit the maximum current to this value. Best test is
to set up a climbing arc or just short out the 14.4 kV (HV) side of
the xmfr and then use a variac to bring in the power slowly. The
reactor is adjusted to match the current you require.

If you don't use a reactor at all the xmfr will try to draw approx
700 Amps and blow your breakers! The current must be limited.

The 15 kVA xmfr is the max. continuous current that your house pole
xmfr can supply. If everything else in the house is shut off, you
can draw the full 15 kVA for short periods of time. Be sure to shut
off current hogs such as stoves, elec. hot water heaters, and clothes
dryers when you run a large coil. A full 15 kVA will probably match
up well with a 24 inch dia. coil running a 40 x 12 inch toroid and a
0.15 to 0.20 uF 50 kV capacitor bank.

When you build a big coil be prepared in advance to spend big bucks
for all the necessary parts to do it right.

We sell the xmfrs for $125.00 if you need one --- I have 60 of them in stock.
