so what uses 34.5kV
it's a voltage used for distributing electricity without too much loss but that's not important right now (it's actually a photograph of a railway electrification thingie and the 34.5kV is the input from the power utility, there's a transformer there and also a buncha rectifiers)
oh, i see! that makes sense
it's pretty involved switchgear because electric rolling stock can eat up hundreds of amps at almost a kilovolt so it's a lot of power...gotta get those trains accelerated and moving :3
We had stuff like that in the basement where I used to work. Inline fuses as thick as my arm. Giant sign on the door to the utility closet that said, "If you touch anything in here, you might die."
This was before the "Not only will this kill you, it will hurt the whole time you are dying," meme, sadly.
honestly the meme is a good description of death by arc flash; the heat and light and blast from being next to a /spark/ involving those voltages and currents will give you enough burns to send you to the ICU and the grave shortly after.
Yep. A non-survivable injury, but not a quickly fatal one. Hideous way to die. My scoutmaster was a lineman and found a guy who'd tried to steal what he thought was de-energized cable once. After he told the story I was afraid of *power outlets* for weeks.
Power company out here has a video online of the safety demos they do for first responders - including frying a hot dog from an arc.
A guy in the Air Force told me once there were radars you could do that with, but that sergeants had *no* sense of humor about the thing. Mostly because you weren't supposed to be standing that close when the radar was active, as it would do the same thing to your innards.
That doesn't surprise me - I know there are a lot of safety regulations about not letting people spend too much time working on cell towers and the like for similar reasons. Not insta-fry under most circumstances, more like the frog in the pot.
yeah RF might not be ionising but it can cook you quite well, stuff like eyes aren’t really designed to dissipate much incoming energy at all
I love it when transit authorities leave the workings of their rectifier substations exposed like this.
that’ll knock ye across the room alright
