Watch this amazing the jobs people do and the skill of the pilot requires amazing trust.

Like the man says there is only 3 things to be afraid of:
Heights
Electricty
Woman
I know which one is the most volatile!!!!:eek: I wonder how he gets is life cover?

You mean a full body silver suit with sparks doesn't qualify? :}

What does it do to the helicopter's electronics?

The compass isn't really an issue when flying VFR doing pinnacle approaches to tall stationary objects, and hover work. In fact, it's the last thing one might reference.
The potential between the helicopter and the wire is achieved by bonding before the transfer of the worker from the helicopter platform to the wires, and then again before returning to the helicopter again. With the potential adjusted, there's no risk to the helicopter because there's no ground from the helicopter.
If the helicopter had a ground to earth, such as a rope or chain hanging from the helicopter to the ground, that would be another matter completely.

Are there no safety issues when they land ? That huge potential difference must go somewhere (even if just to ground there must be the risk of a ruddy great spark!) ?

Only if they land whilst still connected to the wire.

Once they are disconnected then the only issue is the capacitance of the aircraft. You can only carry so much electricity.

Birds do it...
...even educated bees do it.
