A Bright Arc: A Guide to Power Line Safety (Full-length version)

This video deals with the dangers of working near overhead and underground power lines. Dramatic footage and computer animation show what can happen if you or someone on your jobsite accidentally contacts an energized power line. This video is also available in six segments. (1990)

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

This comment is ancient

[@Sc0pee]

These high power lines are scary. I always get chills down my spine from just looking at them. I would never be able to work under them, yet alone LIVE under them like some people are...

[@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

Bags of water

[@onewhosaysgoose4831]

Bags of water filled with vital organs that respond to electrical instructions.

My father was killed working for Chew Excavating in the early 70's......Electrocuted!!!

[@tusharkathuria9]

Hello, Recently there was short circuit in the transformer feeding power to our school and few homes around. The short circuit was caused by group of squirrels. Due to short circuit a lot of electronic equipment got damaged in school. We have mcb installed but I guess they only trip when short circuit happens in output line which they are guarding. In our case short circuit happened before the mcb as transformer is located outside school premise. So wanted to know what all safety devices are available which can be installed in school to provide safety in this scenario. Also if anyone can suggest safety devices for lightning protection that will be great.

[@Duraiamuthan]

There are some options you may consider - Regular tripper in the MCB trips only when there is too much current than expected - I think most of MCBs also have GFCI so when someone gets electrocuted or a significant short circuit the tripper trips - Have A CAFCI this trips when there's an arc inside the building - Have SPD ( Surge Protection Device ) this grounds the too much electricity that comes as a result of Grid failure or lightning strike You may consider to install voltage stabiliser also but this is an expensive option

[@Duraiamuthan]

If you believe your school is in an isolated place & there are HT lines around the area then you might install lightning arrester at the school but be sure to ground the lightning arrester some 20 feet away from the school building.

Watching from fontanan 433 iron workers richards class 4-24-24

[@TheEndOfABloodline]

Had to watch that bunny hop one more time after watching a safety video LOL

[@Nicholas-f5]

A PILE OF CHARCOAL?!

[@crazyman7000]

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

[@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?

[@TheUltimateScot]

Power companies use wood poles because they're relatively inexpensive compared to steel or fiberglass.

[@herbertzausenhaim246]

Watch closely. On top of the wooden poles wires are held by insulators. Insulators are commonly made of glass or ceramics which prevent any current flowing into the wooden poles. So the material for the poles has no influence on the the safety of the pole itself.

[@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).

[@forceawakens4449]

If thats the qualification for an insulator, are there technically any insulators?

[@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.

[@jcincinnati]

Thanx

[@fnorgen]

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

[@form109]

very professional safety video.

[@Muck-qy2oo]

Electricity never takes its way to ground! It always tries to go back to the source.

[@ryank1273]

Get out.

[@Muck-qy2oo]

What do you mean with "get out"?

[@ryank1273]

Muck2014 You have it backwards!

[@Muck-qy2oo]

What? What do you mean? What you are writing is not clearly articulated .

[@ryank1273]

Muck2014 You clearly not American.

[@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."

[@obfuscated3090]

Wrong. Wood in a tree contains water and high voltage isn't the piddly current from a wall outlet.

[@Sc0pee]

A live tree conducts electricity because of its sap and water content. Thus it is advised to NEVER take cover beneath a tree in a thunderstorm.
