A staggeringly large amount of magic smoke was released in the Netherlands today This is an aerial view of an above ground 150kV power line. Yes, the whole above ground line is smoking, over a distance of many kilometers. It's surreal. This is not a forest fire, this is smoke from a glowing hot power above ground power line. https://vxtwitter.com/conscienceai/status/1565699489150783488?s=21&t=PR31ov8bLAK2mMbQPv-Vng The cause can be seen in the video in the tweet. Due to (or at least related to) construction or maintenance work in a substation (there are no reports of dead or wounded linemen, so that's good), a very bad arc was triggered, which arced to ground and phase to phase. There was a 400 to 600% overload on the line that feeded it, causing the line to sag over a distance of many kilometers. The circuit breakers failed to open in multiple places. As of today, it's not yet know if they were triggered but failed to interrupt the fault current, or whether they simply didn't trigger. There was extensive damage to a LOT of electrical infrastructure around the area where the fault happened. Below is a picture of arcing on the 1,5kV catenary line of a train. It is not yet known if the 150kV line directly contacted the train power line because it sagged so far, or whether this is caused by the return path of the 150kV line going through the rail intrastructure. Our rails are not hard referenced to ground, but they do have protection links in many places that short out, if the rail carries a voltage of more than a few hundred volt with reference to ground because of a ground fault.   Signaling equipment along the train line is completely fried. The isolation on the low voltage wires is just gone. Miraculously, only one train carrying 350 people got stranded. The train didn't burn out, which probably means that the 150kV line did not directly contact the 1,5kV train catenary, though the arcing on the power line above does look scary.   In some areas, smoke emanated from the ground where power cables were buried underground. Both rail pictures were 3km away from the nearest power line. Things went really, *REALLY* wrong.  There were no power interruptions lasting more than a few minutes, due to the redundancy of our national grid. However, in the town nearest the fault where the mains voltage dropped because of the overloaded local part of the grid, the local voltage regulators started to try and step up the voltage. This lead to the voltage surging when the fault suddenly cleared, but the regulator still was at a high tap. It took a while for the voltage to get back to the standard 230v. As of yet, the extent of the damage is not known, but there are reports of many small fires or plumes of smoke emanating from stuff like highway signaling equipment, and the trains in that area won't be going anywhere for the next couple of days.

 So are you all going to have to dig up a bunch of buried lines? Because to this armchair idiot who knows nothing about electron fuckling "we saw smoke coming from the ground over buried lines" sounds

Will definitely take a while. They essentially gotta check the integrity of ALL train power supply and signaling cables and equipment along at least 10km of track. I expect them to do isolation and continuity tests and just leave it buried if it passes those tests, but it's safe to assume the trench diggers are gonna be really busy for at least the whole of next week. I'm pretty sure they'll find a whole lot of leaky cables, and especially signaling cable. The 150kV line doesn't have anything to do with trains, the trainfuckling is just a side note in this story lol More importantly, the private companies running the national grid have to figure out why the gently caress this can happen without a breaker opening. A second substation burned out because of the overload. So far no pictures or video of that. LimaBiker fucked around with this message at 21:40 on Sep 2, 2022 |

It depends on whether they can use directional boring to replace the lines. I doubt transmission size stuff can be done without daylighting it.

Underground transmission lines are mega$$$. Ooof I wonder if it was really breakers not opening when commanded by their protective relays or the relays themselves not picking up the fault.

The Lone Badger posted:They can't pull a new cable through the same conduit? Not if the conduit is damaged, it might tear up the insulation. For a distribution conduit you just pull the old cable out and blast the borehead through whatever conduit is already there, and it pulls the new conduit behind it, but there's an upper size limit on directional boring machines. They'll probably run an optical check through the conduit after they pull the old cable to see if they can re-use it. e: And this is assuming that the transmission line was pulled through conduit, some of this stuff is so big that is has to be laid and then a shell built around it. wiegieman fucked around with this message at 00:44 on Sep 3, 2022 |

I don't know how big some of those giant transmission lines are, but I've seen steel pipelines directional drilled that were about a metre in diameter. Obviously you need a big rear end directional drill for that.

A lot of people get combative when being told no, and getting on a cliff top battle with a drunk rear end in a top hat is very low on most people's lists. Seems like dude was suicidal, based on my rear end; but the way he was considering a jump for a minute there.
