VA = Power / Power Factor = 1000 / 0.8 = 1250 VA @ 36.87° Z = (V)(V*)/VA = ((220 @0°)(220@-0°))/1250 @ 36.87° = 38.72 Ohms at -36.87° Hope this helps.

I found something similar in an old valve based oscilloscope. It turned out to be a string of diodes inside it. If it is high voltage then that may be the same. See if you can find a circuit diagram for it or a similar unit. It think it was...
