500KV Substation arc.. Nice
Loading...
Uploaded by bladerunner1268 on Nov 23, 2007
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.

@BerkerIzmir35TR yes
-
Magneficent evil.... Arcing while isolating onload or while isolating current storage devices is a common phenomenon
-
That is cool!!! How did that happen?
-
Woo!
-
is that how Powerstations Turn Off the Power?
-
oh my gosh this changed my life
-
CLICK, KOSHZZZZZZZZZZZZZZZZZZBANG. "...WAH!"
-
I HAVE THE POWERRRRRRRRRRRRRRRRRRRRRRR
-
@BerkerIzmir35TR yes. k= kilo ( a thousand) .. so 500*1000 => 500'000
-
What is 500 kv mean? 500.000 volt?
