A bright arc: A video guide to powerline safety

WOODEN pole?

[mpwelk]

@nessnes64 Makes no difference to this kind of voltage/current.

The best thing is to work naked..

Thanx

[tryithere]

I'm the power line this video warned you about.

this video saved someones life

I like his hat at the beggining. "Im the guy your mother warned you about"

[yoochoooob]

I used to survey UK power lines for a company of tree surgeons specializing in keeping trees/shrubs/hedges etc' cut back to safe distances from different voltage power lines. Anywhere that foliage was really close or touching the lines they had to ONLY use pruning/saw-heads at the end Fibre-Glass rods which had to be rated for the voltages you were working around and they HAD to be checked annually to ensure their insulation was up to scratch. Even seemingly dry wood will conduct HV.

I can't believe i actually saw this entire video.

At 9:49 not true hop until you see others walking lol

[lexichronicle]

ha ha ha ha :P

today i was watching a building getting torn down by a backhoe and there was a powerlne and they were getting close and probally nevrvous some of the builing must of touched it and it was wierd i thought the backhoe touched it if it did theyre would of probally been sparks or something

[form109]

very professional safety video.

[sophiegromit]

There are some fast growing trees adjacent to my yard (neighbors), whose branches are touching the lower and higher lines! I e-mailed the power company, and they said unless there is sparking or arcing, they won't come out! Isn't a branch touching an upper line cause for concern???!!! I have a child that runs around the yard and i'm scared to death electricity will go down the tree to surrounding ground.

[luigi2999]

no, wood is a natrual insulator. The only way wood will conduct electricity is if it is wet. Other than that, your kid should be safe. just don't let him climb that tree. The results if he touched that wire would be very "shocking."

[uploadJ]

_Dried_ wood can be an insulator; growing, live wood is conductive; not so good as copper wire, but, sufficient enough to conduct enough current from a 14KV line to pose a shock hazard to personnel.

Verify: Stick a couple of sharp probes from your ohmmeter into the bark / cambium layer of a living tree and note the resistance is decidely not infinite (qualification for an insulator).

[luigi2999]

well, I do remember now that some wood is a conductor, probably cedar and the like, cuz it's very oily. Also, if wood is a conductor, then how come high voltage transmission lines are mounted sometimes on wood pylons? sure, they have insulators, but cuz of the air breakdown, how come it dosen't arc?

[form109]

The large Distance between the Lines Prevents Arcing....its Easy to see why wood is an option....its Cheap,easy to use and doesnt require the Pouring of Foundations that are nessicary for steel towers.

Some of the advice here is very dangerous and potentially fatal. I would recommend you speak to another proper authority on your particular situation. You child's life isn't worthrising for the advice on youtube.

[BenHutchinson1]

Why does current flow through you if you are on the ground? I thought current just tries to get to ground. Once it reaches the ground, it has no reason to go anywhere else, so it shouldn't need to go through you. Could someone familiar with the science behind this explain it to me please.

[jac00367]

It's allways looking for the easiest path to ground. So in the video with guy walking it easier for the current to go into and out the body vs going through the ground. Why because the closer you are to source the stronger the current is and as you move away the weaker it gets. So by him walking his feet are in aways in two different power level zone so the higher current goes into body (rear leg)and out(front leg)looking for ground. That why he says to keep your feet togather and hop.

[arjunus]

Go to a place where the wires are low.

And take TL ligth tubes en hold them ponted hi.

The are going to glow without conneted them.

I'ts fun. Free ligth

[cipguz]

You guys are professionals. I personally think that you should do this video in Spanish and I will buy all of them. I teach/train OSHA courses and these videos are wonderfull
