Find the current by dividing the output voltage (assuming 14.4kv) into the power
rating:
(note: kva and output ratings are rms)
P/V=I or 10kva / 14.4kv = 694mA
Finally, find the impeadance by dividing the current into the output voltage:
Z=V/I or 14.4kv / 694mA = 20,749ohms at 60Hz (as pole
pig is design for).
Hope it helps,
