AS I surf the forums there is a new Science Channel show on electrical primary distribution, helicopter line men and substation operation.

Immediately after which she made a discrete call to your life-insurance agent.tkb said:I had my wife watch it and told her that was my next job. :grin:
I'd love to see that additional footage...tkb said:It was the same flight as in the video, but parts of the video weren't in the show.
They has a guy replacing a spacer between the two parallel cables, and then Spyder crawled out on to the cables to install damping weights.

Shows like that make me want to subscribe to American satellite...

What matters is the relative voltage difference between the two objects, not either object's absolute voltage to earth. The helocopter's charge would be DC, by the way.ELA said:So, the helicoper is being charged up to the same level as the high lines on approach and this is what creates the large arc?

No path? There must be some path.
Are you saying that the current flows due to capacitive coupling between the earth and the copter?
If so then why doesn't a bird fry when they approach the single line conductor?
Anybody know the capacitance of a bird to the earth? It's gotta be less than that of a helocopter.zog said:. . . why doesn't a bird fry when they approach the single line conductor?
That reminds me of that video where the man says, "...don't forget to change the setting from bulldozer to eyeball."LarryFine said:Anybody know the capacitance of a bird to the earth? It's gotta be less than that of a helocopter.
