500KV Substation arc.. Nice

This video clip was captured by the maintenance foreman of 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, The system contains a non conductive gas which is vented when the circuits are tripped. one leg of the circuit was not working correctly and therefore not quenching the spark with the SF6 (ozone depleting) gas.

Mr. Tesla would be proud.

well there's your problem: the discombobulator aint connected to the whatsydosit that re routes the fistatbular parameter to the trip switch. just insert a googlwhatsit into the flux capacitor and bobs your uncle.

Meanwhile, in a random bar some short distance away: "I need your clothes, your boots and your motorcycle".

N. Tesla actually would utilize such thing and instead of huge arcs he would step down this extra energy from air particles to usable form...

[hunterhauswirth1234]

Simple , the flux capacitor is not fully charged.

But the only thing that can generate enough power (roughly 1.21 Jigawatts) is a bolt of lightning!

[cscsullivan119]

the people who answered your question were incorrect. the air between the two terminals is ionized because current has to flow through. once, the air is ionized, it's a much better conductor than regular air, so the current will continue to flow through it. that path of ionized air gets hot from the current, so it rises, and the current follows it.

At the very end...WHO-

exactly but not like that not even with a 1000km line induction really
