Electricity sub-station explosion

A 132kv Sub Station is one of the scariest places I've ever been

You wanna hear the sound of a 275kv circuit breaker then!

Seeing the issolaters close/open is pretty impressive. They arc from around 60-70cm apart, and thats with the circuit breaker open.

That might have something to do with the fact that isolators are designed to be operated under NO LOAD conditions. Switchs are designed for operation under load conditions or overload conditions but not short-circuit conditions!

You should hear the air blast circuit breakers fire at stalybridge 400kv sub, 3,000psi! Makes the windows rattle :D

Even under no load there will still be a tiny bit of arching, although 60-70cm's is a bit extreme. 400kv will only fizz and crackle for about 50cm's or so, as there is still charge between the open CB and the isolator.
 

Thats a transformer suffering a severe failure! 14seconds in, the oil escapes under pressure and ignites.


And here's the arc effect people are talking about:

Not quite the arc you see on normal everyday switching, lol. That happened under an unusual fault condition, normal isolator arcing is a brief arc with some fizzing and crackling.

Crazy Russians o_O:

I'd hate to deal with electricity (especially those voltages). That stuff scares the jeebus outta me.

If that russian one is real...wtf! how stupid.
 
Ahh my mistake.:)



I dunno, another one by the same user here

Can see how it could be faked. Not sure how the managed to do that if it's real though.

According to someone who replied to the video:

rough translation of description at left

Occurrence of short-term arc at single-phase on ground 110Kv by means of very thin copper wire

I guess they placed wire on the ground below the live wires and it arcs at times?
