GOAB (Gang Operated Air Break) switch on what appears to be 69,000 volts. (40k phase to ground/ 69k phase to phase) switch. This is NOT a load break switch; if you open this type of switch under load, a destructive arc will occur. Complete and utter destruction costing thousands of dollars to repair.
When the insulator broke, you can see the really big arc that stretched out hit the phase where the second switch was on. Phase to phase short caused the switch to fail, most likely because the potential difference between phases is (sqrt 3) times greater than the phase to ground voltage.
Stupid description. There was no phase-to-phase short, it leads to immediate trip of automatic breaker. Switch faulted (or was open without permission) just in same moment when arc appears. Such an arcs occurs under nominal load current (that flows its usual way but now through air because of fault) and it's not about sqrt(3). Plasma channel created because of this melts down steel and cracks insulator (ceramic i guess), that's why part of it falls.
@@user-ui6xt4fd1fI was a child when I wrote that 10-year-old comment haha. I agree it is stupid. Don't know why I thought there was a phase-to-phase short, there clearly isn't. Thanks
WOW! Impressive, and you get a Big High Five for the camera work. I have watched many of these videos in this category, and most of them are "very shaky" ***I am not badmouthing the videos with the explosions(usually at the end) which cause the "shakiness". These can't be helped!!*** Good job and hope to see more videos from you!
Looks like the switch failed to fully open, or failed to fully close, allowing current to continue flowing across the gap until the ceramic insulator cracked under the thermal stress. Not entirely sure why the other switch started arcing at that exact moment, perhaps a voltage transient from the carnage? When too much current is forced through a conductor it begins to heat up: think of the wire in a toaster which glows red when cooking your toast.
I think what happened was one of the isolators or something, for one of the connecting wires finally gave and broke. This guy has a video of what seems to be the different angle of the same pole ua-cam.com/video/yRAWE6pNgqU/v-deo.html
U Think!? You are guessing. You are guessing wrong. I am not an expert, and I don't "guess" on this answer. It's a simple one What you saw on this video, was "cut out fuse", and it "malfunctioned" on it job during an "arc fault"

Mirroxaphene Just asking, but what are one of those switches used for?
Sectionalizing or visual proof of disconnection.
that switch is toast, aka crispy.

@@RadioTrefoil glad that you had learn something 🤝🏻😊
This is a very adorable Power Pole !
Ya :D
Excellent footage.

this is amazing!
Oh thats one awesome arc much bigger than what i get in my garrage lol
@2:20 - It's off now! (clang!)

when it fell i think it went phase to phase therefore tripping a recloser or blowing a fuse.
+Sally Moore if it was a recloser it should have tripped on phase imbalance or some three phase customer was part serviced

Sad it didn't go phase to phase xD
Electricity is a beautiful thing.⚡⚡⚡
Fire was acting as a rainbow!
Wow, Great footage!
Like a burning fire, the switch connection burns due to power surge or overload.
What a massive 💪 power
Is this an S&C electric switch?
Sehr sehr sick
Is the purple glow over the middle line what they call a "corona"?
Pretty sure it's just a lensflare/lens reflection from the super bright arc.
nopes its nt corono
Good footage

WiseProtector72 it isn't a cut out fuse, it's a switch. Pipe down with the shitty smart arse attitude too.
SinistaUK: thank you for saying that. I would have responded the exact same way only probably stronger
Just another job order fix it jew
