Would you do this for a job?

Thats quite a charge they neutralize between the transmission line and the chopper.
The first guy to do that probabally found out the hard way.!

[ger21]

I bet they get paid well.

I actually saw a TV show on those guys a year or two ago on the Discovery Channel

Al do you think the white suit is conductive...a kind of Faraday cage?

I imagine it is a well paid job.

Yes it is.

[thkoutsidthebox]

I'd be more worried about the heights! Thats some day job you have there ynneb!
They mentioned the suit was 75% Nomex Flame retardant, and 25% stainless steel thred. Wonder if its heavy....

[sdopp]

Its heavy only when you hit the ground!!!!!!!!!!!!!

Have only worked on de-energised transmission lines, there were 2 "feeds" of 3 phase, 132,000 volts, one feed per side of the towers, and one side was turned off at a time to allow us to change the insulators. Tricky thing was that the inductance was enough from the energised side that we had to clamp earths similiar as those guys did to bring the line down to earth potential (we didn't have a chopper, did this the old fasioned way ).

Even though there were guys working on the next towers with earths on the line, there was about a 2inch spark when we put our earths on...

Heard horror stories of these same earths breaking and the linesman grabbing the conductor, well you can imagine the result. Amazingly enough he survived and was the one telling me the story.

Have also heard of guys climbing down the insulators (very large ones), to live conductors, by the time they get there, there is no path for the current to pass through them back via the insulator and off they do their work.

I think I saw the same show as Gerry and they said that it takes a certain number of insulator bells to "hold" the line and then 2 extra. The guy was reaching above one of them so he said there was only one bell between him (on the line) and the ground. Doesn't seem like a situation where I would want to be bridging the bells.

When you think about the spark length in the video they must have been up around the 500 kV.

How the heck, do they get past OSHA?

I'll be honest, I don't know much about power lines, how does the current not fry the electronics in the heli?
