Hi Uwe, It may be off beam, but it occurs to me that the current looks 3rd
harmonicy but the voltage doesnt....what if there is insulator leakage at
the high voltage peaks that would pull more current from the feeder on the
voltage peaks ?? I have never had enough power for corona here so i am not
sure what it would look like on a scope. What is it like a lower power
levels ??

Cheers de Alan G3NYK (always ready with a silly question !!)
