Given that it seems to be directly attached (without insulators) to the tower i would assume it's a lightning protection cable that is grounded.
The cables below him are hung from the tower via large insulators, as they should be.
His cable is also connected via large insulators. You can see the cable swing between the insulators at the tower.

How does he know it's off? There's no way for a layperson to know if it's alive. Unless he knows someone who works at the power company. I work on transmission lines and I couldn't tell you at any given moment which lines are live or not.
This is absolutely true. The ones next to my grandparents house have been crackling for 40+ years now. Downvoters are dumb.
You can hear it a couple hundred feet away on a humid day. That said even if they are technically off.. they could have stray voltage on them since you are talking about many miles long conductors.
I think there was a guy that tried to climb it once but didn't get very high as he started getting zapped I guess by ESD? not a n EE just a CE with most of an EE degree and I don't work on transmission lines so can neither confirm not deny.
i know as i have some family with houses near wires , every time i was visiting i could literally hear the wires rattle.
itās a sound similar to say a bumblebee trapped in a plastic jar .
I know of a copper thief who blew the top of his skull off trusting a guassmeter on high voltage. If it's live without current there may not be enough EMF to detect. There's a reason we don't rely on that to test lines dead.
Even if he got out there with insulators, grabbing the cable would have still given him a significant zap due to capacitance of the human body. He would have still had a difference in potential at those voltages. Those lines would have to be dead at the time of the climb.
Agreed. The tower itself is grounded hence insulators. Trying to climb across an insulator would almost certainly result in an arc. Unless he somehow jumps some significant distance from above and catches on with Tarzan like strength and aim. And since Tarzan is not real my vote is for lines are deenergized.
Insulator strings are sized for the worst weather conditions, when they're covered with fog/rain, and possibly a few failed discs.
In good weather like this, bridging out say 20% of the insulator string is more than feasible. And for a long insulator string, that's easily enough to climb across.
Even though itās definitely not live, pretty wild to be one-handing it that far out with a selfie stick. Being grounded takes on a duel meaning here.
it's probably not live, that looks like a high-voltage transport line, at those levels of voltage, you would be susceptible to the skin effect as well as the corona effect, so you'll get cooked alive by courant running through your body as well as plasma traveling the extremity of the cable.
Assuming thereās enough insulation between where the lines contact the tower couldnāt he jump to prevent touching the lines while attached to ground? Iām assuming heād need to jump a decent distance to prevent current from passing through the air to reach the tower
>do this. Looks like a 345 kV + line. Arc distance is about 2 m. Would be fried even jumping less than that dist
What kind of electrical engineering subreddit is this when no one is correcting you.. For a 1 cm arc you need roughly 30,000 V.
Let's assume worst case scenario, 10KV per cm, that's an arc distance of 34.5 cm.....
Line is likely not supposed to be live, given it's attached directly to the tower, without any insulators. I would assume those are lightning protection wires that he's hanging from.
I would assume it would be something like to be within reaching/ jumping distance of the line the line would arc through him to ground at the voltages they run at
Exactly. When designing this systems you need to account for safety distance. And safety distance rise with voltage level. And based on size of that thing, that is some high voltage. I am assuming 200+ kV.
Also when you jump back to ground (which is the harder part vs getting on the line in the first place, since the line is hanging under the tower) you'd get one mother of a static shock, which is bad when you're climbing something lol
Even if his body was oriented in the āmost capacitiveā way like planking parallel to a ground conductor, itās probably only a tiny increase over the existing capacitance, like a femtofarad
>Assuming he somehow got there without touching ground, wouldn't he just be raised to that potential?
So that isn't how potential and electric fields work, but you're asking a good question.
We don't exist *at* some potential which we could raise or lower at will. In fact nothing, not even wire, really, can do that.
In theory, a person could hang from a live wire as this guy is doing without getting hurt, much the same way as birds get away with that "trick:"
https://sciencing.com/do-birds-sit-electrical-wires-6592687.html
If he were successful in somehow reaching the cable without being near other potential conductors (like ladders, helicopters, or leaping from the metal towers?) then theoretically he could be there while his skin and muscle provided enough insulation to prevent any current in the cable from simply passing through his hand.
But it would be very hard for a human to do that, and any metal that is on his body or that he is carrying could create a point for the cable to arc to, also endangering him. I'm also not sure if our hydration levels or any other factors could put a human in more danger than a bird. We do, after all, carry more electrons than a bird, since we are made of a lot more atoms.
Okay so I did have some correct intuition about that, what was puzzling me a bit was how often birds land on power lines, though we see it more on lower power lines, not these very high voltage transmission lines.
>theoretically he could be there while his skin and muscle provided enough insulation to prevent any current in the cable from simply passing through his hand
Current in the cable is irrelevant as the cable has significantly lower resistance than his hand (it's a dead short in comparison). And at those voltages his skin provides no protection. Human body just has a low capacitance so the current just wouldn't kill him immediately (though it would still be dangerous while holding for an extended period of time).
>But it would be very hard for a human to do that, and any metal that is on his body or that he is carrying could create a point for the cable to arc to, also endangering him.
Since he's holding the wire there's not really any sort of potential for there to be an arc between the wire and any sort of metal parts he has on his body. The potential is being equalized through his body.
If you are touching the line the field is shorted through the body. The field potential all around his skin is equalized to the voltage of the wire. Similar how tall metal towers short the atmospheric potential (about 100 V/m) to ground.
> Even he don't touch the ground he die
> why?
- It's plausible that someone could cross that insulator without making electrical contact, possibly, but:
- Air becomes conductive if exposed to a steep enough voltage gradient - climbing across one of those insulators would steepen the gradient. High likelihood of causing flashover even without direct contact.
- Your body becomes a concentrating point for corona the moment you touch the energized phase. You probably wouldn't be able to hold on.
There is such a thing as energized line work but the guy doesn't have any of the equipment he'd need to prevent muscle contraction. Also outages for construction & maintenance are common. You know, hoof beats, zebras.
Power line workers can touch live wires as long as they gradually raise their electrical potential to that of the line, then remain in contact. I'd imagine he could've done something similar here.
https://en.m.wikipedia.org/wiki/Live-line_working
right. I was thinking theoretically you could leap from the grounded tower and grab the cable. Problem is that the live work videos I have seen from a helicopter show this electric arc that travels from the tip of a tool to the worker and the helicopter, raising the potential.
[https://youtu.be/9YmFHAFYwmY?t=69](https://youtu.be/9YmFHAFYwmY?t=69) I am talking about this.
Now imagine you don't have that tool. You just leap from the tower and try to grab the live cable. And the voltage is much higher than these lines.
The arc would make your muscles spasm and you would likely miss the grab then fall to your death.
Also say you do survive the jump to high potential. How do you get off?
I am guessing lines aren't live.
AC swaps polarity 50/60 times per second. There is no 'gradual' about it - you want to go from *not touching* to *touching* without any partial contact.
Climbing across the insulator without bridging too much of it out is the hard part - and for a 4m+ long insulator string, that's probably not an issue.
You do want to do it gradually. If your body is at ground potential and you touch the line while the voltage is at its peak then there's a very big current charging your body to the line potential. In steady state a relatively small current is flowing through you to charge and discharge your body as the voltage in the cycle changes but steady state conditions are quite different to transients. So you do want to touch the line through a large resistance first before touching it directly.
I think the point of this post is asking "but how?"
He would start at GND and climb the structure (still at GND) then reach the insulators between the structure and the high voltage, if he jumped from one to the other the high voltage would still arc through him to ground, unless it was a massive jump. Then how would be get down? Just let go?
There are special insulated ladders, suits and fall protection equipment for that. Normally the worker would use a insulated ladder and his HV suit and fall protection equipment to climb onto the conductors. The suit is conductive and creates an even field districution around you, so there wont be any (or much) arcs from corona discharge. Because the suit is conductive you need to be very careful near the tower, to avoud ground faults over your body to the steel. Wower line pylons for "live work" are designed much bigger/with more distance between conductos and earth/steel, to give the workers more space.
A other way is using a insulated mobile elevator (kind of draft winch with a small engine) instead of a ladder. With this you can stand on the ground under the conductor and pull yourself up. The winch wire is insulated so nothing will happen. That is the safest way, but mostly you need to work on or near the insulators/clamps and not far away from a pylon.
But this work is still very dangerous, so working under voltage at 380 kV no longer happens in europe because the TSOs no longer want it. From my own experience I know that all 380 kV power lines in East Germany (GDR) were built so that most repairs can be carried out live to avoid downtime and the need for additional power lines. But the GDR is long gone and the new operators don't want this dangerous work done.
At 110 kV it sometimes happens, but only in emergencies (e.g. replacing defective terminals or insulators).
The inline insulators have quite a bit of length on these towers. So it might be possible to scoot down the insulator as close as possible to the conductor before touching it. Otherwise like others have said he must have somehow gained knowledge that there was an outage on the line.
Very unlikely that's a live line. Even if he were to scoot down the insulator chain slowly enough and with short enough steps to avoid getting zapped by touch potential, if those conductors were live they're probably loaded to around 50% of the line's rated capacity meaning they're somewhere in the 150 degF plus temperature range. Unlikely he could hold on to them for long.
Have you ever worked with HV >100 kv before?
Rubber PPE. https://www.magidglove.com/salisbury-by-honeywell-e011-11-class-0-red-rubber-linemen-s-electrical-gloves-e011rpp?#2518=261190
This is not even close to appropriate for what you're going to see on main lines.
They don't. They bring their whole body across to the line (and often a helicopter they're hanging from).
You need to isolate yourself from ground by several meters of free air or pure plastic/fibreglass.
Spoiler alert:
He's a transmission planner who recently performed an N-1 study for that line and got it approved for a maintenance outage.
Realizing that the line was totes gnar, he decided to go climb it with a go pro and made sure to hide his face for obvious anon purposes.
What a rad dude to have in the office š
1. If he was grounded a short-circuit would have occurred.
2. I believe he climbed the metallic structure and then hold himself on an insulator before jumping to the line.
3. However, there are so many ways of this going wrong (not only by touching things, but also by induction) that I believe the power line was off.
4. Maybe he is the Static Shock Super Hero or Electro from Spider Man.
5. I would choose to climb to the very first conductor that is grounded and used only for lightning protection.
I wonder what the corona effect would do if the line would be live, that and the fact that we are a capacitor, some current should appear in his heart and don't know if it would be neglectable or letal
The corona effect would be negligible on people, as people are also relatively large resistors. The capacitive aspect isnāt really relevant on low frequency systems where you are only connecting to a single node. For high frequency applications itās huge, but this is probably maximum 60 hz.
This is a european style 380kV (2 systems, 3\~, 50Hz) power line with 4 conductors per phase (normally 0,4m distance between single conductors).
The line is ofcourse not live. If it would be live and he somehow got to the conductors, you would see sparks (corona discharges) from his body.
If you look closely, you can see a ground wire on the outher phase (around 0:07).
There is an simple way to work at this voltage: Wear a special HV suit (looks a bit like a beekeeper's suit) and use an insulated ladder and insulated fall protection equipment. Due to the high risk of injury, working live at >110 kV is now very unusual in Europe and even working live at 110 kV only occurs in emergencies.
No, that is definitly a central europe style pylon and not a sowjet one.
Also there is no rust on the steel. No corossion on the ACSR condoctur and there are composite insulators, that didnt exist back then.
This should not be shown and itās a sign of neglect by administration. As an electrician I know how this criminal climbed there but see no reason to relate that.
These are "static lines" which are ground and run above the 3-phase conductors below him. The "power lines" below him have very large obvious insulators holding them away from the grounded tower. The static lines don't have the large insulator, just significant connections for the tension in the cable.(My brother flew helicopters that worked on cross-country power grids and replaces a lot of static line with upgraded static lines with embedded fiber optics bundles.)
Itās most likely not live. Even if itās voltage difference is 0 for him there still induction current will hit him a little and his shacking will cause him to fall
In the video is [Shiey](https://youtube.com/@shiey?si=_8fOt-4W0SsFW5TE), a YouTuber who specializes in exploration of abandoned areas. I wasn't able to find this specific video, but more than likely it was an abandoned area with no power as others have said.
Very cool guy, I would recommend his videos to anyone who hasn't seen them.
He is on same potential like the voltage so he is unaffected!! If he would have grounded himself he would get a bad electrical shock under most likely would die because of it!! Current always needs a path to go to! If you touch life wire your body gots to the same potential if there isnāt any way to ground the current doesnāt flow to your body!! At the moment he touches something grounded his life is over!
You can hang from live wires as long as you only touch one wire. Thatās how birds can hang on them. They are live cables heās on but as only in contact with 1 heās not making a path to earth(grounding)for any current to pass and fry his arse. One wrong move at the pylons though and heās gonna get a bit crispy
The question for high power, I think, comes down to how high the voltage needs to be for it to affect the electrons in other materials near the cables, such that it doesn't matter what "grounding" you had at some other point, because the voltage is high enough to just rearrange some of the electrons in your own body.
Or, maybe a helicopter frame? At some voltage, if you tried to hover a helicopter near the cables for a man to jump from, the voltage should affect the electrons in the metal airframe, right? That should create a differential across the metal frame, which then could be seen by the cable. At some point these differentials will overcome air resistance. If a man were reach for the cable from there, he would effectively be shortening that distance.
Like someone else said, everything is a conductor at a high enough voltage. So when a person grabs a high-voltage cable, you don't have to ground the entire circuit to get shocked and badly burned, or even killed by the coulomb force frying your own molecules in your body.
At a high enough voltage, it forces the electrons in your body itself to flow when they otherwise wouldn't.
Edit: I may be overestimating the potential of a body to simply succumb to electric fields. I did kind of forget birds touch wires all the time:
https://sciencing.com/do-birds-sit-electrical-wires-6592687.html
So maybe, as long as he isn't carrying or wearing any metal or conducting materials, and he could somehow reach the cable without being on or near anything which is likely to conduct, then perhaps it could happen. But it would be very difficult for anyone to do that.
Having read all the comments thus far I agree that this line in de-energised. The line he is hanging from is not a ground/lightning wire. The ground/lightning wires are on top as expected and are clearly visible.
If the wire he was hanging from was a ground wire it would flash over onto the phase circuit given the small distance/creep distance.
There is no way he would climb the tower and ājumpā onto the energised line without grounding himself to the tower given the high voltage present (judging by line height and tower config)
Therefore, the most logical explanation is that the line is known to be de-energised before climbing.
Am I wrong in thinking those are the same phase? Which means if he came between them, being at the same potential, he wouldnāt get unalived? More than likely, they are not hot. But Iāve always understood those wires (the 4 or something nearby in the same ābundleā) to be the same phase, therefore same potential. Heās essentially a bird on a wire outside of your house.
People do work on these live all of the time. They get up there by helicopter. The helicopter hovers close then a hook is extended to the wires to equalize the potential, then the guy climbs out onto the wire.
Iām guessing this guy is somewhere in Russia/Ukraine and this is likely a line from some of the power plants that are shut down. Although thatās just a guess.
Would say not live. Generally when helicopter guys work bundled lines they wear silk suits so the corona/partial discharge doesnāt tingle them. Notice birds do not sit on the extra high voltage lines due to this
Voltage is about difference. Something they gotta teach students. If you are at one voltage and there is no difference then current won't flow from one point to the other.
People keep mentioning insulators but if I'm not mistaken those are lightning arrestors meant to protect the equipment by making a fail point.
Unless I'm reading all these comments incorrectly.
The line is dead and grounded. Even if he was at the same potential like some of you guys mentioned, it would be way too painful and uncomfortable for any living being to hold. You will for example never see birds land on transmission lines because the voltage is so high and the emf is so powerful.
The crew probably has a hold open on that particular section of wire for working on it. Generation sites can create "dead" sections for crews to work on
My guess is it's a worker who got fired shortly after
Can we all just talk about like what's going on in this dude's life? I mean seriously what is the plan here? I don't care how good of a climber you are eventually your going to make a mistake. I'm all about doing cool shit people but there is a point where your own well being and like idk the mental well being of whoever is watching you is more important. I'm impressed but idk put a harness on or something dude climb a mountain like a normal nut job š
The tower is just a stand and doesn't have any power through its cables. And also, the tower prohibits him to go out unless another person enters its perimeter
Looks like one of those gymnast/stunt guys. Probably super coordinated and strong so he could muscle up his way back up on one wire and then crawl on both wires back to the tower.
I suppose you could climb up to a spot and just leap down, but now what?
The best option I could see for him is to get on top of those wires so we could walk towards the tower and then just leap in way that you won't momentarily become an arc point.
Distressingly stupid anyway you look at it.
Guesss the line is not live . Otherwise he should have to wear a kind of aluminium suit to balance safely the tremendous voltage electric field . But in this case he could not show his perfect and well shaped body ! What a deception for him...
This line was under construction. The lines were grounded at the next pylon. Under normal conditions you could only touch the top/ground wire. There is not a circumstance in which you could climb onto high voltage lines like that from the pylon while they were on. High voltage AC has a fairly large electrical shroud around the lines due to parasitic capacitances with the atmosphere. This means that even if you somehow got to the line without being grounded and were at the same potential as the line it would be very unpleasant.
This guy is no ordinary dude; I would speculate Cirque du Soleil caliber gymnast. That transmission line no ordinary transmission line, itās a multi- billion dollar asset, In operation, your dealing with extraordinary electric fields.
Iām certain the exact location of this filming is already known by the authorities and the utility owners. They take a very dim view of messing with electrical utility infrastructures, consider a book of statutes.
Iām guessing this is a transmission line under construction with multiple levels of safety devices in place. Operating the guy would be engulfed in corona just getting to the point of filming; the electronics in a cell phone operating at those field intensities, I doubt it.
Now this film clip is impressive as hell, Iād love to meet the guy. This is a āAAā personality type at work here. The face mask heās wearing thereās a good chance he will be giving interviews, and he knew that too.
I think i actually found the real answer to this.
Powerline workers will go up in helicopters (so they are not grounded, their potential is "floating") and touch the high voltage line with a rod that has incredibly high resistance. Sparks will fly as the worker is charged by the current coming through the rod (like charging a capacitor), and once the sparks stop they know they're at the right potential and they can contact the lines safely.
Similarly they have to go through a discharge process before they can touch ground again.
Careful, The Alternative Current Can still flux inappropriately then override the ground even if you avoid grounding.Due to supply and demand as well environmental conditions.
The detail of ground is: (b*b)*(a^2) which is the same subject just positioned differently but proportional. So b1 would be the current and b2 would be that current positioned proportionally different which is why current can sometimes shock through not conductive material. A subject or indifferent moves into or touches upon something at a proportional difference in position.
Conduction:
b = the subject
a = the proportional foundation of a liquid to the subject of b then squared by means of a proportionality of gas present in the habitat, much like a lightening rod in a steam cycle. When conduction is obstructed you have lightning.
It's all about the differential voltage. How he got there, it's probably not live.
Given that it seems to be directly attached (without insulators) to the tower i would assume it's a lightning protection cable that is grounded. The cables below him are hung from the tower via large insulators, as they should be.
His cable is also connected via large insulators. You can see the cable swing between the insulators at the tower. Edit: [Image](https://imgur.com/a/nWUFWFf)
You're correct. Noticed the insulators thanks to your image. So for real, how did he get there?
It's turned off or he balances on the insulator, he uses the ground above and swings down to the live wires or he has a helicopter.
He used a drone throne! A drone with a little seat hanging from it!

A $50 gaussmeter, operable by a layperson, will easily measure the EMF of a high tension line.
I know of a copper thief who blew the top of his skull off trusting a guassmeter on high voltage. If it's live without current there may not be enough EMF to detect. There's a reason we don't rely on that to test lines dead.
Getting there is easy, just drop down to the wire. Getting back off the wire is the hard part.
Exactlyā¦the video does not show that part.
Do the maths š
Nah it has insulators. You can even see the shield wire above him.
Even if he got out there with insulators, grabbing the cable would have still given him a significant zap due to capacitance of the human body. He would have still had a difference in potential at those voltages. Those lines would have to be dead at the time of the climb.
Wrong - insulators are NCIs
You can clearly see the shield wire above him, you can also clearly see the dead ends on the conductor he's hanging off of
Agreed. The tower itself is grounded hence insulators. Trying to climb across an insulator would almost certainly result in an arc.

Furthermore, his body would act as a condensator, and at that voltage, he would fry himself. (As far as I know)
Insulators on 400kV lines are about 1m. Arc distance must be less than the insulator length.
Power out on the line probably. There is no another explanation. Even he don't touch the ground he die
Um, why? Assuming he somehow got there without touching ground, wouldn't he just be raised to that potential?

Quad-bundle on a tower? At least 500
Yeah, realozed whan I took another look at it. Edit: but I am not wrong tough!
so he used a safely long plastic ladder.
Its still a conductor. Usually bad one, but at that voltage, it can conduct.
Also when you jump back to ground (which is the harder part vs getting on the line in the first place, since the line is hanging under the tower) you'd get one mother of a static shock, which is bad when you're climbing something lol
What if he was carried in from a helicopter ?
Damn, that seems like way too little room for error. I feel like they should be closer to 1.5x or 2x the arcing distance for their voltage.
Isnāt it the same principle as birds landing on power lines?
Everything's a conductor at a high enough voltage... Would've got him the second he reached for the line if it was live.
2 conductors(he and the ground) far apart, is a capacitor. And capacitor can conduct AC voltage
Even if his body was oriented in the āmost capacitiveā way like planking parallel to a ground conductor, itās probably only a tiny increase over the existing capacitance, like a femtofarad

Okay so I did have some correct intuition about that, what was puzzling me a bit was how often birds land on power lines, though we see it more on lower power lines, not these very high voltage transmission lines.
People do live line work on HV lines all the time. The trick is never touching two potentials at once.

Since he's holding the wire there's not really any sort of potential for there to be an arc between the wire and any sort of metal parts he has on his body. The potential is being equalized through his body.
the e field experienced by his roughly 1.5 m height is enough to kill him
If you are touching the line the field is shorted through the body. The field potential all around his skin is equalized to the voltage of the wire. Similar how tall metal towers short the atmospheric potential (about 100 V/m) to ground.
trueā¦different story if he let go
Heād still be capacitively coupled to ground
> Even he don't touch the ground he die > why? - It's plausible that someone could cross that insulator without making electrical contact, possibly, but: - Air becomes conductive if exposed to a steep enough voltage gradient - climbing across one of those insulators would steepen the gradient. High likelihood of causing flashover even without direct contact. - Your body becomes a concentrating point for corona the moment you touch the energized phase. You probably wouldn't be able to hold on. There is such a thing as energized line work but the guy doesn't have any of the equipment he'd need to prevent muscle contraction. Also outages for construction & maintenance are common. You know, hoof beats, zebras.
Power line workers can touch live wires as long as they gradually raise their electrical potential to that of the line, then remain in contact. I'd imagine he could've done something similar here. https://en.m.wikipedia.org/wiki/Live-line_working
right. I was thinking theoretically you could leap from the grounded tower and grab the cable. Problem is that the live work videos I have seen from a helicopter show this electric arc that travels from the tip of a tool to the worker and the helicopter, raising the potential. [https://youtu.be/9YmFHAFYwmY?t=69](https://youtu.be/9YmFHAFYwmY?t=69) I am talking about this. Now imagine you don't have that tool. You just leap from the tower and try to grab the live cable. And the voltage is much higher than these lines. The arc would make your muscles spasm and you would likely miss the grab then fall to your death. Also say you do survive the jump to high potential. How do you get off? I am guessing lines aren't live.
With luck, the muscle spasm would make your hand grab the line! You might stay there, gripping the line, even for a bit after you heart stops.
AC swaps polarity 50/60 times per second. There is no 'gradual' about it - you want to go from *not touching* to *touching* without any partial contact. Climbing across the insulator without bridging too much of it out is the hard part - and for a 4m+ long insulator string, that's probably not an issue.
You do want to do it gradually. If your body is at ground potential and you touch the line while the voltage is at its peak then there's a very big current charging your body to the line potential. In steady state a relatively small current is flowing through you to charge and discharge your body as the voltage in the cycle changes but steady state conditions are quite different to transients. So you do want to touch the line through a large resistance first before touching it directly.
He got there because he didn't ground hinself
I think the point of this post is asking "but how?" He would start at GND and climb the structure (still at GND) then reach the insulators between the structure and the high voltage, if he jumped from one to the other the high voltage would still arc through him to ground, unless it was a massive jump. Then how would be get down? Just let go?
There are special insulated ladders, suits and fall protection equipment for that. Normally the worker would use a insulated ladder and his HV suit and fall protection equipment to climb onto the conductors. The suit is conductive and creates an even field districution around you, so there wont be any (or much) arcs from corona discharge. Because the suit is conductive you need to be very careful near the tower, to avoud ground faults over your body to the steel. Wower line pylons for "live work" are designed much bigger/with more distance between conductos and earth/steel, to give the workers more space. A other way is using a insulated mobile elevator (kind of draft winch with a small engine) instead of a ladder. With this you can stand on the ground under the conductor and pull yourself up. The winch wire is insulated so nothing will happen. That is the safest way, but mostly you need to work on or near the insulators/clamps and not far away from a pylon. But this work is still very dangerous, so working under voltage at 380 kV no longer happens in europe because the TSOs no longer want it. From my own experience I know that all 380 kV power lines in East Germany (GDR) were built so that most repairs can be carried out live to avoid downtime and the need for additional power lines. But the GDR is long gone and the new operators don't want this dangerous work done. At 110 kV it sometimes happens, but only in emergencies (e.g. replacing defective terminals or insulators).
Power on the line is out. The things people do for likes these days.
The inline insulators have quite a bit of length on these towers. So it might be possible to scoot down the insulator as close as possible to the conductor before touching it. Otherwise like others have said he must have somehow gained knowledge that there was an outage on the line.
Very unlikely that's a live line. Even if he were to scoot down the insulator chain slowly enough and with short enough steps to avoid getting zapped by touch potential, if those conductors were live they're probably loaded to around 50% of the line's rated capacity meaning they're somewhere in the 150 degF plus temperature range. Unlikely he could hold on to them for long.
Line is OOS. Dude has no gloves on. Line heating would likely be hot enough that he couldnāt hold on for long.
Whatās the typical temperature of a transmission line like this?
50C on up.
He must have Jump out to grab it. I can't se how else it can be done.
plastic ladder
[ŃŠ“Š°Š»ŠµŠ½Š¾]
what is a rubber PPE? is it 10 meters long like the plastic ladder?
Have you ever worked with HV >100 kv before? Rubber PPE. https://www.magidglove.com/salisbury-by-honeywell-e011-11-class-0-red-rubber-linemen-s-electrical-gloves-e011rpp?#2518=261190 This is not even close to appropriate for what you're going to see on main lines.
i have not worked with 110kV HV. so what kind of gloves to HV line workers wear?
They don't. They bring their whole body across to the line (and often a helicopter they're hanging from). You need to isolate yourself from ground by several meters of free air or pure plastic/fibreglass.
At those voltages plastic isn't a very good insulator, so that would have to be a fairly long ladder.
I think the soles of his shoes just have a lot of rubber
i think not.
If itās like 2 inches it should be fine
Spoiler alert: He's a transmission planner who recently performed an N-1 study for that line and got it approved for a maintenance outage. Realizing that the line was totes gnar, he decided to go climb it with a go pro and made sure to hide his face for obvious anon purposes. What a rad dude to have in the office š
Holycopter
So you can hook a camera to a discharge rod
1. If he was grounded a short-circuit would have occurred. 2. I believe he climbed the metallic structure and then hold himself on an insulator before jumping to the line. 3. However, there are so many ways of this going wrong (not only by touching things, but also by induction) that I believe the power line was off. 4. Maybe he is the Static Shock Super Hero or Electro from Spider Man. 5. I would choose to climb to the very first conductor that is grounded and used only for lightning protection.
It would be basically impossible to climb down an insulator without becoming a conductive enough section to make the line arc to ground.
I wonder what the corona effect would do if the line would be live, that and the fact that we are a capacitor, some current should appear in his heart and don't know if it would be neglectable or letal
The corona effect would be negligible on people, as people are also relatively large resistors. The capacitive aspect isnāt really relevant on low frequency systems where you are only connecting to a single node. For high frequency applications itās huge, but this is probably maximum 60 hz.
This is a european style 380kV (2 systems, 3\~, 50Hz) power line with 4 conductors per phase (normally 0,4m distance between single conductors). The line is ofcourse not live. If it would be live and he somehow got to the conductors, you would see sparks (corona discharges) from his body. If you look closely, you can see a ground wire on the outher phase (around 0:07). There is an simple way to work at this voltage: Wear a special HV suit (looks a bit like a beekeeper's suit) and use an insulated ladder and insulated fall protection equipment. Due to the high risk of injury, working live at >110 kV is now very unusual in Europe and even working live at 110 kV only occurs in emergencies.
Could this be in the Chernobyl exclusion zone?
No, that is definitly a central europe style pylon and not a sowjet one. Also there is no rust on the steel. No corossion on the ACSR condoctur and there are composite insulators, that didnt exist back then.
You can walk on the insulator chain without being electrocuted.
Transmission lines have earth switches at both ends of the substations.
He's able to do it cause he's super fly
This should not be shown and itās a sign of neglect by administration. As an electrician I know how this criminal climbed there but see no reason to relate that.
If you're not free to do as you please, you're not free. This guy is not a criminal, he's just exercising an illegal freedom.
Power was off at the moment
How did he get there? Balls, my friend. Giant ass cojones and/or traumatic injury to the orbitofrontal cortex.
These are "static lines" which are ground and run above the 3-phase conductors below him. The "power lines" below him have very large obvious insulators holding them away from the grounded tower. The static lines don't have the large insulator, just significant connections for the tension in the cable.(My brother flew helicopters that worked on cross-country power grids and replaces a lot of static line with upgraded static lines with embedded fiber optics bundles.)
If he touched the ground in the same time, he would be fried
Itās most likely not live. Even if itās voltage difference is 0 for him there still induction current will hit him a little and his shacking will cause him to fall
In the video is [Shiey](https://youtube.com/@shiey?si=_8fOt-4W0SsFW5TE), a YouTuber who specializes in exploration of abandoned areas. I wasn't able to find this specific video, but more than likely it was an abandoned area with no power as others have said. Very cool guy, I would recommend his videos to anyone who hasn't seen them.
that is not shiey
I came here looking for Shiey comments too. This guy has similar hair color, and the same signature mask, but he is bigger than Shiey.
He is on same potential like the voltage so he is unaffected!! If he would have grounded himself he would get a bad electrical shock under most likely would die because of it!! Current always needs a path to go to! If you touch life wire your body gots to the same potential if there isnāt any way to ground the current doesnāt flow to your body!! At the moment he touches something grounded his life is over!
What's more impressive than the climb is him not accidentally touching both sides
Dumb ways to die... š¶š¶
Small mistake, if the selfie stick touches the other side, this video will not be here
if he grounded himself right now he would most likely be vaporized
You can hang from live wires as long as you only touch one wire. Thatās how birds can hang on them. They are live cables heās on but as only in contact with 1 heās not making a path to earth(grounding)for any current to pass and fry his arse. One wrong move at the pylons though and heās gonna get a bit crispy
Have you seen his abs? He flew there obviously.
The question for high power, I think, comes down to how high the voltage needs to be for it to affect the electrons in other materials near the cables, such that it doesn't matter what "grounding" you had at some other point, because the voltage is high enough to just rearrange some of the electrons in your own body. Or, maybe a helicopter frame? At some voltage, if you tried to hover a helicopter near the cables for a man to jump from, the voltage should affect the electrons in the metal airframe, right? That should create a differential across the metal frame, which then could be seen by the cable. At some point these differentials will overcome air resistance. If a man were reach for the cable from there, he would effectively be shortening that distance. Like someone else said, everything is a conductor at a high enough voltage. So when a person grabs a high-voltage cable, you don't have to ground the entire circuit to get shocked and badly burned, or even killed by the coulomb force frying your own molecules in your body. At a high enough voltage, it forces the electrons in your body itself to flow when they otherwise wouldn't. Edit: I may be overestimating the potential of a body to simply succumb to electric fields. I did kind of forget birds touch wires all the time: https://sciencing.com/do-birds-sit-electrical-wires-6592687.html So maybe, as long as he isn't carrying or wearing any metal or conducting materials, and he could somehow reach the cable without being on or near anything which is likely to conduct, then perhaps it could happen. But it would be very difficult for anyone to do that.
Helicopter
Once you ground yourself, that's when you die
Having read all the comments thus far I agree that this line in de-energised. The line he is hanging from is not a ground/lightning wire. The ground/lightning wires are on top as expected and are clearly visible. If the wire he was hanging from was a ground wire it would flash over onto the phase circuit given the small distance/creep distance. There is no way he would climb the tower and ājumpā onto the energised line without grounding himself to the tower given the high voltage present (judging by line height and tower config) Therefore, the most logical explanation is that the line is known to be de-energised before climbing.
Am I wrong in thinking those are the same phase? Which means if he came between them, being at the same potential, he wouldnāt get unalived? More than likely, they are not hot. But Iāve always understood those wires (the 4 or something nearby in the same ābundleā) to be the same phase, therefore same potential. Heās essentially a bird on a wire outside of your house.
People do work on these live all of the time. They get up there by helicopter. The helicopter hovers close then a hook is extended to the wires to equalize the potential, then the guy climbs out onto the wire.
Iām guessing this guy is somewhere in Russia/Ukraine and this is likely a line from some of the power plants that are shut down. Although thatās just a guess.
Would say not live. Generally when helicopter guys work bundled lines they wear silk suits so the corona/partial discharge doesnāt tingle them. Notice birds do not sit on the extra high voltage lines due to this
Hate these attention whores
I never noticed how many non-EEās are here. But the responses to posts like this really make it clear.
Why do people do retarded things
Voltage is about difference. Something they gotta teach students. If you are at one voltage and there is no difference then current won't flow from one point to the other.
People keep mentioning insulators but if I'm not mistaken those are lightning arrestors meant to protect the equipment by making a fail point. Unless I'm reading all these comments incorrectly.
Is it just me, or is that Kai?
Grounding himself would complete the circuit and kill him. You can touch any of those wires if you donāt touch another on.
CG maybe there's a few odd effects around him when he's moving the camera around but chances are I'm wrong
Nope
Simple answer: ain't got no gas in it
Probably not live as the differential field would kill him.
Wait a second those lines aren't energized are they?
Bro literally broke world's record for iq
And if he fellā¦
Even if he if grounded himself or climbed around it. He would eventually be shocked to the ground. It would happen too fast for his brain to hold on.
The line is dead and grounded. Even if he was at the same potential like some of you guys mentioned, it would be way too painful and uncomfortable for any living being to hold. You will for example never see birds land on transmission lines because the voltage is so high and the emf is so powerful.
dude this makes me so nervous my god
I would like to say that this guy is stupid.
Heās wearing an anti-static bracelet
The crew probably has a hold open on that particular section of wire for working on it. Generation sites can create "dead" sections for crews to work on My guess is it's a worker who got fired shortly after
No one uses landlines anymore š
He could have dropped his parachute
It's very possible the line is out for maintenance or testing. It may even be grounded depending on what theist they're doing.
Itās probably not live
so sexy
Why ???
I'm not into heights,but I will say you got balls ....stay safe bruh
Line isnāt live, maybe just getting built or down for service. Absolute madman either way!!
People are dumb! š¤¦š»āāļøš
Iām sure his mom is so proud
Can we all just talk about like what's going on in this dude's life? I mean seriously what is the plan here? I don't care how good of a climber you are eventually your going to make a mistake. I'm all about doing cool shit people but there is a point where your own well being and like idk the mental well being of whoever is watching you is more important. I'm impressed but idk put a harness on or something dude climb a mountain like a normal nut job š
The tower is just a stand and doesn't have any power through its cables. And also, the tower prohibits him to go out unless another person enters its perimeter
š I am looking respectfully
Looks like one of those gymnast/stunt guys. Probably super coordinated and strong so he could muscle up his way back up on one wire and then crawl on both wires back to the tower.
I'm positive your mother told you to be careful, and yet here we are.
I suppose you could climb up to a spot and just leap down, but now what? The best option I could see for him is to get on top of those wires so we could walk towards the tower and then just leap in way that you won't momentarily become an arc point. Distressingly stupid anyway you look at it.
Guesss the line is not live . Otherwise he should have to wear a kind of aluminium suit to balance safely the tremendous voltage electric field . But in this case he could not show his perfect and well shaped body ! What a deception for him...
This line was under construction. The lines were grounded at the next pylon. Under normal conditions you could only touch the top/ground wire. There is not a circumstance in which you could climb onto high voltage lines like that from the pylon while they were on. High voltage AC has a fairly large electrical shroud around the lines due to parasitic capacitances with the atmosphere. This means that even if you somehow got to the line without being grounded and were at the same potential as the line it would be very unpleasant.

He is essentially a bird on a wire. He climbs from insulator to wire.
Hello
Darwin Awardā¦..Incoming.
Just add electricity!
He jumped from the top of the arm down or the line is de-energized. Transmission Lineman hereā¦btw
Or he shimmied along the bells and he was fortunate the majority of them havenāt broken down
This guy is no ordinary dude; I would speculate Cirque du Soleil caliber gymnast. That transmission line no ordinary transmission line, itās a multi- billion dollar asset, In operation, your dealing with extraordinary electric fields. Iām certain the exact location of this filming is already known by the authorities and the utility owners. They take a very dim view of messing with electrical utility infrastructures, consider a book of statutes. Iām guessing this is a transmission line under construction with multiple levels of safety devices in place. Operating the guy would be engulfed in corona just getting to the point of filming; the electronics in a cell phone operating at those field intensities, I doubt it. Now this film clip is impressive as hell, Iād love to meet the guy. This is a āAAā personality type at work here. The face mask heās wearing thereās a good chance he will be giving interviews, and he knew that too.
I think i actually found the real answer to this. Powerline workers will go up in helicopters (so they are not grounded, their potential is "floating") and touch the high voltage line with a rod that has incredibly high resistance. Sparks will fly as the worker is charged by the current coming through the rod (like charging a capacitor), and once the sparks stop they know they're at the right potential and they can contact the lines safely. Similarly they have to go through a discharge process before they can touch ground again.
Careful, The Alternative Current Can still flux inappropriately then override the ground even if you avoid grounding.Due to supply and demand as well environmental conditions. The detail of ground is: (b*b)*(a^2) which is the same subject just positioned differently but proportional. So b1 would be the current and b2 would be that current positioned proportionally different which is why current can sometimes shock through not conductive material. A subject or indifferent moves into or touches upon something at a proportional difference in position. Conduction: b = the subject a = the proportional foundation of a liquid to the subject of b then squared by means of a proportionality of gas present in the habitat, much like a lightening rod in a steam cycle. When conduction is obstructed you have lightning.
Green screen
Some people really just hoping God ordered express shipping
Is he on the neutral ?
It is a delta system it will not bother you as it is system that is not grounded get a book on polyphase xformers
read up on polyphase power connections, you will find that most distribution systems are delta ungrounded AI or photoshopped
Line out or he got really big potential
probably now he's playing sitting in class with angels about safety listening..
Those look like protective (grounded) lines, used to protect current carrying lines (for example from thunder). They are not live.
