Possibly the coolest video ever....500kv substation

The story I heard about this.

This switch we see opening is an isolator switch that is in series with a load break switch.

Normally the load break switch would be opened first then the isolator switch. The load break switch was not working so they had to open the isolator switch with the load still on.

So it was expected but not normal operating conditions.
 
Couldn't watch the videos (slow dial up connection :mad: ) but there was some awesome pictures.:cool:
Thanks for both of the links.

Bob, get high speed. You'll never regret it. Trust me.

DSL (on existing phone line) or cable (if you have cable) are cost-effective.
 
The atmosphere is clearly a conductor as can be seen from this video. Based on this I propose we should start "Atmosphering" ("Heavening" in the UK) electrical distribution systems such that we connect either the system neutral, or one of the phases of a delta wired transformer system to the air, to limit the voltage imposed on it during a fault. We would need to drive 8' long copper clad rods into the heaven, and also in order to safely protect against any potential differences between metal objects and the heaven, we need to place electrodes and connect to secondary services at a common point that is directly connected to the grounded conductor of the service. Read more about it in my upcoming book entitled "Macmikeman Atmosphering Electrical Distibution Systems For Safety" :grin: P.S. Also remember, we should not ever depend on the atmosphere to safely clear a fault, but rather we should always have a low impedance path back to the source.

Bob you hit the nail on the head, Switches for high voltage are self contained under a vaccum filled with an inert gas called somethinghexaflouride (too many years since I worked for a POCO).

What you are seeing is a switch opened with a load on it.
 
Not under actual load..

Not under actual load..

Before I read the link that Roger posted I thought this line was under an actual load when they tried to open this switch. According to the link, it was only the "magnetizing current associated with the line reactor" that it was trying to break. Can you guys imagine what kind of arc it would have produced if it was more than just line reactor current??
