12470Y/7200 "wye configuration.."

I always post then, go looking for the answer to the question I 
asked. I have done some reading and it seems that the wye config. 
applies to only (3) phase transformers. Wye is called wye because 
that is what the wiring diagram looks like....a "Y". I learned that 
in a wye config., you will get 1.732 (sq. rt. of 3) times the voltage 
across phases as you do from phase to ground/neutral. that is why the 
transformer I found says 12470Y/7200. 7200 * 1.732 = 12470 
volts..Now..I have a question. Is it ok to use a (3) phase pig @ 
12470 volts wye to run a tesla coil?.I don't see a problem...You just 
don't use one legs...I don't think you would even have to feed it (3) 
phase. If so, all you need is a (3) phase motor to manufacture the 
3rd. leg. Any comments will be appreciated...Thanks...Chip Ford
