I've heard that. I thought about going ito transmission when i started here, but kind of glad i went the route i did. Good catch on the no load switch.
It's been on the net since early 2000's You can see it's only one phase - one of the breakers on the ring bus had a bad(stuck contact)
I have to hand crank them open - you're not supposed to look up(potential flash burn) - but as soon as you hear the bacon frying you crank as fast as you can. There is a piece of grating grounded to the switch metal that you stand on so if things fail to ground you're at the same potential as the switch = no current flow. I had some backup opening the stuck one last week, with smartphone videos running - someday I'll be on Youtube
... "but as soon as you hear the bacon frying you crank as fast as you can." ... ... I'm sorry Basod, but you guys are crazy as chithouse rats... ... Jeeeeeezz that's funny...
Yea I've seen it before. Never paid that much attention to it. Like I said the highest we work is 34. Even those switches when they fail can be impressive. Did they teach you guys not to inhale if you do look up?
My understanding of it is if a flash occurs and you breath in you can burn your insides, lungs, esophagus, trachea and such.
The kind of juice you guys deal with is spooky. There'd be no problem with me breathing in around that kind of stuff... cause I wouldn't be able to breathe anyway...
Ozone & superheated metal vapors as well. For switching disconnects 115kV & 230kV, grounding etc, have to wear 10cal coveralls, hardhat w/arc face shield. You don't look up just because of the burn potential - think welders retina burn I have 100cal/cm suits for the actual dangerous stuff - racking breakers in/out of 4160V buses The arc flash potential on the secondary of a 230kv to 4160V transformer is crazy high - have a remote racking device so I can stay 25ft away.... never gave a second thought to racking them in/out in my younger years kneeling directly in front of them
It really isn't all that bad Stinny. Get into distribution voltages 480V 3ph where relays are limited at best and you get the below
Well... that was fun. BzzzzzzzzzzzzAPPPPP... as I've said before, seems all you guys who play with fire don't seem to sweat much...
The way I understand parallel wiring is that you're not supposed to use the outlet to pass the current to the next device. I thought you're supposed to pigtail all three (common, ground, and hot) in the box, to the input, output, and pigtail wires that go to the outlet itself. I think I was either told that or read it in a wiring book. Reason being is that half the outlet can go bad and cause this exact issue. Had it happen in my basement this past winter as well; the PO had used the push-in connections on the outlet for all the commons and hot wires and put both grounds to the same screw. I went ahead and replaced the outlet because it had burned the tab between the two sides on the hot side of the outlet.
