Pool Pig...

Ok...there are many kinds of transformers out there. Seems that the 
really BIG coils use a pole pig. Such as "The green monster". His is 
a 15kva @ 14400 volts. Using the math KVA = ((VOLTS X AMPS) / 1000), 
I came up with an amperage of @ 1.042 Amps (15,000 watts). Since .001 
Amps is equal to 1ma, he has 1042ma. According to my calculations, 
the resonant cap is @ .1919 uf. I think he said his cap was 
.1uf...close but not real close..Now, I think alot of the line 
transformers have a selector switch on them. I think they are like 
7200, 6400, 5600 volts for the ones around here. So, if I have 15 kva 
transformer @ 7200 volts, it will have an amperage of @ 2 amps 
(2000ma)(15,000 Watts). At this rate, my cap is gonna be around .75 
uf. This is really high and from a few calculations that I have made, 
A secondary coil 12" 81/2" dia. 48" tall will need over 10000 turns 
of #39 awg. wire on it. This pretty much makes this transformer 
unusable. Besides that, where is a hobbest ever gonna find a cap? Am 
I missing something here? Are my calculations incorrect? Am I looking 
at the transformer incorrectly? Please comment...Chip Ford
