pole pig question

I will use the example of a 14.4 kV, 10 kva units. I know that the 14.4kv 
means, 14,400 volts out. But, what does the 10kva mean? I think it is amps, 
but what does the kva mean? Also, when we use pole pigs for tesla coils, we 
have to use some sort of current limiting. If you use a variac, won't that 
change the voltage going in, thus changing the output power of the pole 
pig? How do you figure out how much power is really comming out of the pig 
to find out how many caps you need? One more question, on the pigs, their 
are 3 inputs (well, i guess outputs in the wild) and 2 outputs (inputs in 
the wild), since their are 3 inputs, which two do you use for 2 phase current?
Thanks
