Greg,
	My 7.2kV 10KVA pigs HV winding measures 23 ohms. It's 220V
winding is under 0.01 ohms.

To check it out, apply a low voltage to the 220V winding, say 1 to 6
volts AC, and measure the HV winding. 6 volts in will give you 300
volts out.

For a HV test, build a jacobs ladder on the HV side and use several
hundred watts of lights as the ballast in the 240V side, or some
heating elements - space heaters, clothes iron, electric charcoal
starter....

	cheers,
