[QUOTE=Kidd;42758683][B]This was a high impedance electrical arcing fault. Usually the upstream protective device (ie. fuse, relay/breaker, recloser, etc.) will interrupt these types of faults and prevent them from continuing. They can start because of tree branches or animals or lightning strikes or anything that can bridge two phases or a phase and ground.[/B] [B]The air becomes ionized and no longer acts as an insulator but a conductor.[/B]This arc is interesting because it was able to be sustained for such a long period of time. If the fault has a high enough impedance, the current is actually not very high in comparison to regular faults. This makes it very difficult for the protective device to clear the fault since it the current can even be lower than the normal "load" current. The utility should be able to analyze any event reports in the area from the relays to try and determine what happened and if it can be prevented in the future.[/QUOTE] Explains it, thanks. [editline]5th November 2013[/editline] Although I still find it very weird and fascinating how it travels like that
Shit i wonder how many miles did it go.
[QUOTE=Rixxz2;42758984]Explains it, thanks. [editline]5th November 2013[/editline] Although I still find it very weird and fascinating how it travels like that[/QUOTE] The reason if I'm not mistaken, is that as the short travels, the heat from it burns away the insulation on the 2 phases (the two 110v lines feeding your home). I'd imagine that would only be a part of it though. I'd like to think it started from a transformer blowing up causing this kinda crazy feedback, there are a whole lotta' trees in the area so it coulda' been from that.

But yes, as you and Mysterious Mr.E said, that's probably one of the reasons.

It was unlikely that it contained insulation as that is expensive to add and difficult to maintain.
what the fuck why do things like that exist terrifying but still i thought it would be floating down the street
Was that a cat near the end just watching the entire thing?

It was unlikely that it contained insulation as that is expensive to add and difficult to maintain.[/QUOTE] Most residential power lines have some insulation, it depends on the place i suppose. Pretty much all the power lines around here (Florida) have insulation, mostly to keep birds and squirrels from detonating when they land on/run across the line. Wind can push arcs, if its strong enough, it seems to me at least to be some kind of coincidence the wind would be traveling the same way the line is for that distance. From what I can see, theres two "hot" lines, and the arc was just following them. I don't see any obvious insulation though.
I actually saw the lights of that since I live pretty damn close. It was crazy, a friend of mine saw that and almost shat his pants.

Phase cross-overs are awesome.
I think it traveled down the line because the arc burns the wire, so the electricity moves to a cleaner bit of wire. It's just trying to follow the path of least resistance.

My dad said something happened like this when he was younger, he said a hawk landed wrong on some powerlines, caught on fire, caused a huge surge like that, and then set the whole hillside ablaze :v:

Something similar happaned outside my home. I heard a noise and ran outside, but i missed mosed of it, i saw lots of sparks and bright light, then kinda lika a small bang and lots of flying sparks everywhere. I barely caught it, but the sounded lastet for at least 15-20 seconds so i guess the sparking did too. Crazy shit.
