Scarey for one person but still kinda cool for everyone else!
More like “someone throws tree branch on power lines”!
It doesn’t look like there is a tree tall enough nearby for a branch that size to fall across it with no leaves or smaller twigs.
Obviously the first gut reaction is to say someone threw a branch up there to make a cool YouTube video, but since we have no evidence of that…
@DerGreg: this here is another example- http://www.youtube.com/watch?v=kVXi_0H_ZzM
Actually everything conducts electricity… but not the same amount.
At such high voltages only ceramic blocks electricity.
I had that happen in my backyard once. Was a much bigger piece of wood. Made a hell of a racket and lit up the entire house at 3am. It was raining like crazy or else the falling fireball would have set the back 40 on fire.
May I know exactly what happened there? It looked like the branch was sitting between the live and neutral lines, then…. what?
I find it unlikely that someone was out in their back yard filming their cat or whatever at just the moment that this happened
looks cool but don’t do it again
It isn’t so much the wood conducting electricity as the moisture in the wood. The whistling sound is the moisture escaping (as steam) as it’s heated by the current until it reaches that critical point when a full blown arc appears across the lines.
IIRC it’s the sap that conducts the electricity.
What interests me is that it doesn’t arc until the wood combusts. Presumably the flame itself has very low resistance and started the arc.
