Can one (or more) of our high voltage electrical experts further explain how this works?
I don't get the arc part, where it appears a rod 'earths' to the helicopter...
and if the helo went away for any reason what would happen to the guy on the line?
I assume this practice is quite safe, or they wouldn't do it, wonder how much they get paid? (The hardest part of this job would be learning how to become a tight rope walker?)

It's not to earth it, but to equalize the electrical potential of the wire and the helicopter.
don't like the idea of having to straddle and crawl along those wires, they should have a ELECTRIC GO KART:D
the could have racesQuote:

It's why you can't be electrocuted in a Aeroplane, but still be hit by lightening. That is where my knowledge stops:D

Fantastic.
I think what gets overlooked is how good the chopper pilot is.
I have inspected HV lines from a chopper a few times as part of my job.....but I have never climbed out :eek:. We remove the door on a chopper then I put on a full harness and lean out the door to scan the lines with an nfrared camera while the chopper flies at about 50m above the lines.
when i went through the training to do it we had little baskets that we attached to the cable to stand/sit in but i never got to do it as i moved to a better paying job
the cage is known as a faradays cage after the dude who created it, google faraday and you'll find heaps of infoQuote:
