500,000 volt line opened under load

This is the 500 kV Eldorado Substation near Boulder City, Nevada. It shows a three-phase motorized air disconnect switcher attempting to open high voltage being supplied to a large three phase shunt line reactor. The line reactor is the huge gray transformer-like object behind the truck at the far right at the end of the clip. Line reactors are large iron core coils (inductors) which are used to counteract the effects of line capacitance on long Extra High Voltage (EHV) transmission lines. Internally, this line reactor has three coils, one for each phase in the three-phase system. Each coil within the reactor can provide 33.3 Million Volt Amperes of compensating inductive reactance (MVAR) at 290 kV between each phase to ground . The power company had previously encountered difficulty interrupting one of the three phases when trying to disconnect the line reactor. The substation maintenance crew set up a special test so that they could videotape the switching event, and they also made arrangements to "kill" the experiment, if necessary, by manually tripping upstream circuit breakers.

Don't you mean the circuit is being 'closed' under load? It seems the arc would be greater if the circuit is closed under load...........

i am done

why does it kinda "grow", and tend to go up and its all curved? I mean i though electricity was always trying to reach its destination as quick as possible?

@jwul28 because what you're seeing is not electricity, it's super-heated plasma that the electricity is being conducted through, and hot air (or in this case, hot plasma) rises.
