Powerline| Electricity| Electrocution| Powerwire| Video Collection

Ekka · 27th November 2007, 10:37 PM

This is a thread collection of videos all about incidents with power lines. From training to accidents etc.

This one is instructional demonstrating different materials placed into line contact 7200v line.

YouTube - power line demonstration

http://www.treeworld.info/video/powe...onstration.wmv 6min 31.31mb WMV

This one here shows a guy "hot suited" to work on lines. Note the arcing with the chopper. These are 500kv lines I think.

YouTube - high voltage worker uses helicopter to reach power lines

www.treeworld.info/video/hotsuitchopper.wmv 3.11min 6mb WMV

This is a drugged crazy line walker getting zapped, apparently survived the fall too.

YouTube - what not to do on power lines

This one here if you look carefully on the slow motion replay shows a branch brushing into the wires right behind the guys head lighting up the street.

YouTube - Large Electrical Explosion Live on News

http://www.treeworld.info/video/larg...lexplosion.wmv 1.53mb WMV

This one is a 500Kv switch arcing, nice leaps!

YouTube - High-voltage disconnect-switch arcing

www.treeworld.info/video/highvoltagearc.wmv 354kb WMV

This one is interesting, something about a wire splicing technique and a big bang goes with it.

YouTube - Power Line Blast - Impressive. This is Safe?!

www.treeworld.info/video/powerlineblast.wmv 1.17mb WMV

Anyway, as you come across them please stick them here, they'll be handy reference later. I'll pull off WMV versions as precautions to links going down in time to come.

Ooh! I like the one with the guy wearing the Faraday "hotsuit". Workin up on those big lines. That actually looks fun. I'd like to know how you get the job doin that.

a_lopa · 28th November 2007, 02:07 AM

I worked at the same company that 2 guys got burnt bad,one guy lived and had to wear a wetsuit type thing..not nice

Ekka · 28th November 2007, 02:14 AM

Therrin

Remember this thread and this post.

To touch, or not to touch

Now with the hotsuit when the chopper was both dropping him off/ picking him up and pulling away the guy used the probe and you could see the arcing to the chopper yet the chopper wasn't earthed.

Similar to step potential on the ground.

I'll keep an eye for more vids Eric but watching those is enough to make any one cringe.Oh btw the one where they were demoing here in lakeland proved a theory of mine that even if it doesn't spark a limb or tree rubbing the lines is energized and unsafe to climb.Is it true that you can get cancer from working near h.v?

Therrin · 28th November 2007, 12:46 PM

Ekka,

yes, I saw it arc'ing out at him. I promise not to work near high voltage lines... at least until I get a hotsuit and chopper =)

Cancer and HV, not proven and coincidental.

Magnetic fields of high voltage power lines and risk of cancer in Finnish adults: nationwide cohort study -- Verkasalo et al. 313 (7064): 1047 -- BMJ

But this UK study shows some statistical difference.

HPA Press Statement | Childhood Cancer and Distance from High-Voltage Power Lines

However over here many people in a building got cancer and they haven't really nailed the problem.

Hope new study will unlock ABC cancer cluster mystery - ABC News (Australian Broadcasting Corporation)

ABC Message Board - Australian Story Guestbook - Messages

Could be the dish outside, the lighting inside etc ...

In either case, there would have to be some reason. Remember the movie Erin Brockovich, the defendants were also trying to claim statistical coincidence.

I personally believe that there would have to be some cellular impact, cells themselves have energy and electromagnetic fields most likely do something to them over the long term.

newguy18 · 28th November 2007, 07:01 PM

Heres one it has nothing to do with trees but it is just another reminder for those of us who do or have gotten close to power that it will kill you.

Ekka · 29th November 2007, 12:44 AM

Survived the electricity and the fall! Bugger me.

newguy18 · 29th November 2007, 12:28 PM

heres another one.
YouTube - 50000 Volt Accident

Ekka · 29th November 2007, 07:18 PM

"Rescuers were told power was cut"

Yeah right, and the poor bastid got zapped.

Unless you see grounded earths in dont assume shit!

If some "expert" tells you it's definately off, tell him to bugger off till the grounding rods are in.

Fact is, even if it is off, 1km away a truck hits a power pole bringing down lines. An energized line now contacts your "switched off" line ... BINGO, YOU'RE ZAPPED.

Trust no-one, see grounds in for your own life's sake, anyone wants to argue, send them up!

newguy18 · 29th November 2007, 09:20 PM

I think I'm gonna go in to get certified lone clearance so i can do around the lines where I have trees that are in peoples yards beside power.

bigshea13 · 7th January 2008, 11:28 AM

ive seen some pretty amazing things not only in line clearence but also as a comercial electrician. lines are silent killers. my brother got complacient and didint put a rope in before felling a 60 foot oak. as he started his back cut he saw that it was hollow. the tree fell across the trani lines. the lines are designed to blow off a certain amount of debris{branches/small trees} most of the time they will blow several times then the faults will kill the line. because the substation was going threw renovations it was set in manual mode. the linesmen had to physically shut it down. by the time they reaches the station the tree had been blasted numerous time. i cant remember exsctly how many times but it eventually caused the tree to explode into flames.
another time a young man just starting out{1yr or so} was felling alongside the kvs. something went wrong. they found him in a kneeling position as if frozen in time. there was nothing left of him except a charred figure. the nearest they could figure was that he was trying to pull the tree back on course after an inital poor cut. im sure there are hundreds of misfortunate stories. bottom line.......pay attention and dont cut around them unless your trained to understand the basic properties of electrity and how it behaves.

This isnt about lines but the how electricity liked this tree. LiveLeak.com - Lightning strikes a tree right near video recorder
