A Man With A Plan posted:*Ring* It's beautiful when it begins to fault phase-to-phase (between the lines). It's like an angel rising. Here's a video: https://www.youtube.com/watch?v=2EJAin4Wiw4 Apparently that area was for the static reactive (or static VAR) compensator. Basically you have big capacitor and reactor (electrical, not nuclear) banks you can switch into and out of the power grid. Switching in capacitors contributes a leading power factor (current sine wave is "ahead" of the voltage sine wave) and switching reactors in contributes a lagging power factor (current lags behind voltage). Someone went really bad in that section and caused all hell to break loose. One of the components was a harmonic filter, and that burned down. Also it looks like the arc that started was in the 13.8kV section but the big arc that it contributed to was in the 230kV section. Some documentation on the fault and why it happened. Harmonics had a big part to play in what happened. http://www.redalyc.org/html/2033/203338783008/index.html Three-Phase fucked around with this message at 02:26 on Jan 5, 2016 |

Question about lethality of electricity, guys. At work sometimes I surge test stator coils, and depending on the coil it's anywhere from 2000 to 15000 volts. It's just a larger version of alligator clips sort of, I hook onto the leads coming out of the coils. It's pretty easy to not shock yourself, you have to hold a foot pedal down the whole time to keep it flowing. I asked some people at work but they aren't experts either, however a couple have somehow managed to touch it before and they said it doesn't even really hurt when it touches you. I'm guessing you'd need to know the exact model of the surge tester, but I can't recall it off the top of my head. All I know is it is AC Coils we test(although it may not be AC coming from the tester. I do know it doesn't matter which clamp goes on which lead so I'm guessing it's AC power). Can someone explain the deal with this? I hate being ignorant of things and there also seems to be a lot of misinformation out there. Like the whole "its watts that get you, not volts!" not always being correct.

It's still a good couple of feet at least from the top stair of the HD ladder to the platform above. So they built some intermediate steps out of whatever scrap wood was lying around.

Good point. They moved their pile of worthless scrap wood to the top of the new stairs.

I haven't looked at those links yet but I will here shortly. Thanks! here's how I think of it: voltage is a measure of the efficiency with which current travels through material. Impedance of material is reduced at higher voltages. current is a measure of the efficiency with which a bunch of electrons (called a coulomb) transfer energy & do work. watts are a measure of actual work done. stuff people say all the time which never helped me visualize it Volts times Amps equals Watts - if you break it down to component SI units, things actually cancel out. various unhelpful analogies about dams, pipes, etc. find one that works for you. real world examples: high voltage low current systems - like the electric potential generated by rubbing your feet on carpet in winter (a few thousand volts, a millionth of an amp) - can make massive sparks that make you say OUCH but don't even twitch your muscles. 15k volts and .4ma is a stun gun: throws enough current into your meat sack to seize muscles, but not enough to kill you (usually). low voltage high current systems - like a car battery - need a wire the size of your thumb to send an appreciable amount of juice anywhere. but there's lots of juice there for ya. enough to weld with if you have heavy leads only a few feet long. anyway the short answer is that anything can kill you if it seizes the muscles in your heart.
