I was there that day. That is one of the transition stations for the Maritime Link. You guys did a good job! I remember you lost one of your drones though.
Did it fry or did they actually lose it? I assume they must spike one end of the wire into the ground and attach the other end to the drone via a length of non conductive material (fishing line?) and then fly it into the wire?
В 88 году Кирилл Мешков (бабушка его была преподаватель литературы и русского языка) из 6а класса 89 школы г. Кемерово затестил трамвайные провода таки же образом, умер от 80% ожогов тела, хоронили всей школой. А так да, мы кидали проволоку на линию 330 киловольт, такой же красивый коричневый дым. Может кто и вспомнит толстяка Кирю, я почти забыл бы его, если бы не увидел это видео.
Why are there only two HV lines on the circuit being tested? In the background I see a "normal" 3 phase circuit. Is this a HV DC inter-grid tie system? Do you know what the live voltage and the fault current are? In Russia kids do this with a rope and a wire, with no PPE, knowledge of step potential, safety or common sense. Nice video.
That line is the one in question. Distance to fault location and protection system test. They could also be testing the effects of mutual coupling on the 2 lines.
It certainly is dramatic when you feel the bang go through your chest from a couple hundred feet away but it's the only way to do it. AVCI specializes in this kind of test method.
I noticed that too. Confirmed by the lack of multiple half cycle hum in the arc. Of note, the short was initiated by copper wire. Can tell from the color of the copper oxide cloud. Other metals produce different oxide colors.
@kleetus92 Thanks for nothing Cletus, (Not a typo). That's nothing but a name for a technique: if I told you that I arrived at a concentration of Metals in a sample by using ICP--AES would you be able to understand that?. Not without looking it up on CZcams I'll bet. Now as a chemist I know what that is. But that's only because I am familiar with jargon from my field. Now it doesn't take a genius to figure out what ground fault is and what a drone is but the question is what the fuck is being protected, how was the conductive path energized Etc. A name is nothing-- it is merely a name and not an explanation . And frankly there's no need to be snotty about it . That's why I called you Cletus .
Greetings. I'm Vic from the CZcams channel rSlash (800k+ subscribers). Thank you for sharing this awesome clip with the world. May we please have your permission to use your content for publication? Of course, we will put your name on top of the video, mention you in the credits and paste a link to your page/channel/account in the description. Respectfully, Vic.
the high contrast near the edges and the funky movement@@SeeMeRolling i see regular fire quite often, although i don't often see electric discharge. that's probably why it looks fake to me, even though it isn't fake.
I like how they had the second guy translating into Canadian. Very inclusive ...
Epic nitrogen dioxide cloud. Classical synthesis from air nitrogen and oxygen.
Thanks for the information. This is exactly the answer to the question I got immediately after watching the smoke.

And vaporized copper
No nitrogen dioxide cloud. Copper wire vapors.
@Based_transition_Clocker Thank you. I thought transmission lines were aluminum due to costs.

That little tingling tells you it's working. :D
Electroboom: Better find my skigloves for this!
Danger, danger, high voltage!
The way we touch.
Shocking!
Same sound as if they had knocked off a bee hive by shooting it
Wrap some copper wire around a ball bearing and then chuck it at the railway power line.
I know I would.
Crazy salt trail

I think it's kind of short circuit test of an MCB... Here maybe they are testing the proper functioning of thegrid MCB.
Hi Anurag, you're correct. Our testing confirms the accuracy of fault locate algorithms and safety/protection systems built into the grid.
Cool!!!
Must be a hair thin wire
Maybe they're testing the functioning of relays or circuit breakers
No. This is an hvdc link. It was the testing of the protection system of the thyristor valves.
Earth fault relay should be tripped
what happened there, arc from ground to phase.

Exploding wire phenomenon?
0:15 sounds like a 20mm
How do you trigger this to happen for testing
ya what the ...
hvdc line?
I noticed that too. Confirmed by the lack of multiple half cycle hum in the arc. Of note, the short was initiated by copper wire. Can tell from the color of the copper oxide cloud. Other metals produce different oxide colors.
@@isettech It's literally lightning...
definitely must be this HVDC
It’s look like thunder
"Lightning"
It's line to ground fault know
What is sams hill was that
This is a process that we've refined for conducting line fault location tests. It's done intentionally to create a short to ground.
Normally a power line has 3 or 6 or maybe even 9 wires on a “PYLON” but my question is that why do this power line only have 2 lines?????
HVDC
test complete !!

- FIVE!
- five?
- FOUR!

- THREE!

- TWO!

Canadian always sounds like a question. He's just interpreting what the American engineer is saying

What would Benjamin Franklin do to perform this kind of test ?
whatda ya think, fly a kite.
@@robertboykin1828He probably would. If he knew how strong electricity was, though, he'd... probably get the hell away from said kite!
There was nothing going from the ground to the wire... ?
5Volts?
3v3 processor
Kucch samajh nahi aaya,
So if you walked underneath that with a fault like that, you could be electrocuted
It would make a lot more sense if you told us what the fukk was going on.
It was written in English. What part of "Drone Ground Fault Testing on a high-voltage power line." was confusing to you?
@@kleetus92so is a cable from ground getting connected to the phase/live
