I would think the primary would trip due to the fault. It looks like time to roast some marshmallows with a long stick!

I've seen this video before and I'm surprised that the operator didn't get electrocuted or that it didn't burn the cable in two where it hit the power line.

The whole time I was watching that I was thinking they should not be looking at that and he finaly said it at the end of the video.

Not only should they have not been looking at the arc, but the spectators should not have been standing in proximity of the overhead wires. By all rights those wires should have burned off and would have fallen dancing around on the ground until the fuse popped. Those wires are a minimum of 13,000 volts and any one of those people could have been killed should the wires have burned and dropped.

Thanks for posting!

I once had a friend of mine that worked at the plant with me. Her husband ran over a power line in this dump truck. He got out of his truck and got his self in between his truck and the power line. Was killed instantly!! So guys be careful around those power lines. Call 911 when you need help
Thanks for all the help form this site

As long as we're on the subject, this would be a good time to remember that there are electric lines undeground too. Having your bucket in contact with one when you step off the machine could ruin your day.

Power lines are bad news.. My father got popped by one a few years back. while installing street lights, working over head in a bucket truck. He survived got burned up pretty good.
the only thing that saved him was the fact that when the power lines arced out, it ruined the hydraulics in the truck so it immediately dropped to the ground. He was about twelve feet from the lines. Never made contact.

What about lightning? Running a blade with a storming approaching would give me the willys. More than once I've stopped and lifted the blade off the ground to wait it out. Never heard of one being hit, however I had a tool pusher tell me that when drill rigs are hit it can mess up the bearings by arcing across them. Rigs are usually well grounded when the drill string is in the hole.

Im not sure how the power lines are run in your neck of the woods, but down here in Aus if a line drops to the ground it will cut out after a few seconds. It will then re-energize after a set amount of time. It will then try for a third time before finally cutting out. I was told it works this way in the event that a tree branch shorts a line temporarily it wont cut power indefinitely until a service tech gets out there to re-energize it.

I found this out after I was watching a cop stand near a fallen power line, keeping people away from it. The line was happily lying there on the ground when it re-energized about two feet away from the cop. It sounded like a small explosion going off and the flash was quite impressive. The cop shat his pants, then stood a little further back.

I think you can just left click the pictures now, and the videos will play in Windows Media Player... some are rather interesting.

Yes, there's some pictures of a crane and power lines too...
