Pool Pig...



Original poster: "Chip Ford" <chipford@xxxxxxxxxxxx>

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
