Peter , all

as I understand it high voltage insulators are make corregated to stop
what you are talking about. With a DC voltage the charge "creeps" from
top and bottom and when it meats a flash over is started. The
insulators are made corregated to give a greater surface area making it
harder for the static charge to bridge. I do not know if a similar
thing happens at say 200 KHZ though.

Feel free to correct me on this.
