  • Its a 345,000 volt switch being opened. its what supplies power to your home but by then we knock it down to 12.5kv. The higher the volts the farther the (spark will fly) notice it didnt cut out till it hit the lines above and blew the circuit

  • at one point the arcs form the outline of Rosie O'Donnell if you are squinting.

  • @RoarDaemon

    I think it'd take more volts, rather than amps. Image electricity as water: volts is the pressure, watts is the amount of water per unit of time, and amps is how fast the water flows. that's high-school physics talking there, though.

  • So would it take a large amount of amps to send an arc over a large distance? I think thats whats happening, seeing as they had a safety device on it, but thats entirely my uneducated opinion TBH :P

  • eino lahklülitiga on ka normaalne koormust lahutada ju:D

  • If only I knew how this switching is done, I would know the process of it.

  • Sorry I babbled on - this is the high voltage equivalent of pulling the plug out of the wall.

  • Yes - switches or isolators is a better word to use. They are not meant to make sparks. As the contacts open, 345,000 Volts are still trying jump the gap by air - starting as soon as the contacts disconnect. This causes a spark which ionizes (and heats) the air making it conduct electricity. This is why pylons have big insulators! bigger insulators - bigger voltage! High voltage is needed - otherwise power is wasted with lines heating up, it keeps current(amps) low. Watts = Voltage x Amps

  • what are those things switches?? and what do they do beside making sparks?
