I have a question about live power transmission line repair using a helicopter. If the helicopter is obviously isolated from ground, why is there a visble arc from the wand to a conductor before the repairman clamps on?
I know the short answer is that the helicopter is brought to the same potential as the conductor, but why doesn't an arc flame a bird about to land on a line? I scoured the web on this, couldn't find anything.
