Cross post from the BMW thread: I think the reason behind the strange noises and lack of handbrake on my e46 has been found.  All the stuff on below the wheel brace fell out when I took the passenger side disk partially off, the piece above fell out the drivers side. stump fucked around with this message at 22:52 on May 11, 2014 |

kastein posted:That looks like one of the kinds of vehicles where the seats fold down to let long objects go through the trunk into the back seat area. Like, for instance, skis. With how everything is torn it makes me think the tire blew up in the trunk and the burst of air blew all the foam and upholstery off the seat frames in its haste to reach the open atmosphere. The rest of the album makes it look like it's a third-row seat in a van or large crossover. Fucknag posted:If it was the 2.0 it was literally the exact same engine as mine, so I'm not surprised. Nah, it was a GT with the 2.5 V6. Some of it was a bit goofy from the PO swapping the US-spec KLDE for a Japanese-spec KLZE, but the majority of the factory harness was intact and was most of the problem.

An air break switch like that one sounds like a shotgun if you're standing right underneath it when it pops open. You can feel it in your chest. Substation safety training has terrified me of ground gradient too.

I've seen an electric arc steel mill operating from about 150' away, it sounds about the same. If you've never been that close to an immense amount of current it's a hell of a thing. You practically feel your skull buzzing at that frequency. Of course the steel mill the sound was mixed with small explosions and quite the lightshow projected onto the roof.

(lightshow starts at 1:30 or so) https://www.youtube.com/watch?v=_j2jESz7Zl8 The heavy cables you can see hanging from the left side of the screen toward the arc furnace are the 3 phase supply lines to it. It's running at 80 megawatts and 80kA, which implies an operating voltage of around a thousand volts. See how they sway and bounce? That's not because the machine is moving, it's from the intense magnetic fields produced by 80 loving thousand amps. Every time the arc flashes suddenly and the cable shakes it's because the current dropped abruptly and then came back when the arc hit a gap in the pile of scrapmetal inside the vat, and the magnetic field abruptly changes too. Which shakes the cable. You know, the 3-6 inch thick cable... yeah each of those (many, many) cables hanging from the wall to the arc furnace is several inches thick. It's really something. Those kinds of plants (as well as aluminum smelters and refiners) are typically located very nearby to their power generating stations because of the gigantic load they represent. They often have to call the power company up and time their smelting operations so that the power company can bring power output up at the same time, else it'll cause widespread brownouts or blackouts. kastein fucked around with this message at 06:40 on May 12, 2014 |

I got to tour Cat's foundry* a while back and while it didn't have a furnace the size of the one in the video it was still pretty rad. Every number used to describe an arc furnace is just so loving huge and the very concept of melting large quantities of metal but just dumping electricity into it  *Engine blocks the size of a car fresh out of the mold are still pretty loving hot when you're 20+ feet away from them.

I don't know about domestic plants (our domestic powergrid is pretty retarded) but Asian mills often have the power plants right on site, to cut line losses, and because the mills often predate the rest of the local power infrastructure. IIRC the Japanese used some of their mill power to supply the grid after the tsunami. The Koreans and Japanese do a lot of much smarter things with their powergrids, but to some degree that's a luxury that was afforded by minimal to no legacy generation and transmission to support.

That said, hearing the thing start up is something else. It's a big synchronous motor, and if you want to get an idea of what it sounds like: https://www.youtube.com/watch?v=1zyhQjJ5UgY The very start, with the industrial humming and whining, is as close as anything I've heard to it.

On why you shouldn't gently caress around with 3phase. Ever.  https://www.youtube.com/watch?v=4bBvmPRqfmo I don't see any of him left. Edit: Also, have a substation meltdown. The arc melts through everything in its path until it boils over an oil filled transformer and you get the giant fireball. https://www.youtube.com/watch?v=fzbQjd_Oo4Q SocketSeven fucked around with this message at 17:20 on May 13, 2014 |

Exit Strategy posted:That's a mechanical SUCCESS, though - The spark's suboptimal but not out of tolerance for the equipment. The failure's in one of the two smaller switches to the right of the big air switch. There are two of them in series to split the voltage stress of opening, and they're inside bottles of sodium hexafluoride to quench any arcs. The idea is that those switches open *rapidly* to break the circuit (which runs to a bank of power factor regulators off to the right), and then the big air switch opens, and then the little switches close again. The rightmost switch fails to open, so when its partner does open, it can't stop the arc and the current just flashes across, so the circuit's still live when the air switch opens (you can stop the video and see the arc across that switch prior to the air switch opens and starts the big arc). What kills the arc is that the utility guys were there specifically to track down what was going on, and one of them manually pulled an upstream breaker. If they hadn't been there, that arc would probably have kept going until it arced to ground or another phase.

Breaker was either defective, not open, or something shorted across the bus bars. Either way, big boom, dead person, lots of damage to the equipment. The really bad part is neither person was wearing appropriate PPE. Person racking it in probably never knew what hit them.

ReptileChillock posted:bike polo is hard on bikes, especially on handmade components from South America Yeeeeeee. Considering the sorts of maneuvers they do, that looks like a very painful failure (not that it'd be great just riding on the street, but you know what I mean.) Either a mechanical or chemical failure: the little synthetic fabric woven around the edge of my month-old sun screen is disintegrating and shedding grey poo poo all over my interior, presumably from heat buildup at the top of the windshield.

Something in that unit arced, and the resulting explosion turned him into chunky salsa from the resulting heat and explosive pressure wave as the copper went nearly instantly from solid to gaseous state. It's one of the things they terrified us with in my electrical training courses, because it doesn't really have any warning signs, you just screw up and explode.
