Little Isolater Fire

When we first heard this we thought the HV transformer had a fault. Fortunately it was the electrical isolation Switch.. result lots of noise, smoke and sparks.. I would certainly NOT have been so close if it had been the txfrmer.
By the time any Authorities - Fire or Utility - had arrived, the fire and arcing had ended.. for some locals it was 10 mins of light show..

Well that will be the last time I fire up that welder at home.

Nice capture mate & thanks for posting~!. I am amazed I never saw this before (I have watched thousands of electrical failure videos over the years). Can only reckon KZbin's search/recommendation system is wonky or something.

Excellent. 💙 T.E.N.

We had a transformer behind work just a couple days ago that blew up causing a blackout on that side of town. I think they said it destroyed the transformer on the pole. Dark as shit walking through the parking lot

[@williammoses6232]

every calls the fire department. did it occur to any one to call the power company so they could repair the problem? they would have been my first call

[@GlennHurse]

In Australia.. we need to Call 000 (112) our emergency call number, this is step one.. while the Supply distribution company is not on the call list, they are called by default. Reason? You do not have to carry the emergency call number for the Power distribution company - aside I have tried that at time and I get a quicker response when I go through the 000 than calling the distributor direct.

you call that little??

[@jdpinbaytown]

50Hz can tell by the sound

[@ktg1012]

I do not think the frequency range is 50hz, because it supposed to be 60 hz

[@wyokaiju992]

@@ktg1012 This isn't the US guy. Its Aus, where they use 50Hz

[@GlennHurse]

Can confirm, our local AC supply is 50hz. AU/NZ

Like fire

[@nickythurman5822]

what?? Isolator switch?

[@GlennHurse]

Yes - HV Isolation Switch - not sure of correct designation, this is the 11KV to the transformer

Cerviços da companhia de eletrificação mal feito que poderia ter desarmado os fenolites e não aconteceu isso

omg

[@lluismiranda2785]

277/480Volts short circuit PHASE TO PHASE.

[@GlennHurse]

Correct Phase-Phase thanks to a bit of moisture and a lot of dust. The Isolation Switch was on the high side of the transformer, ie the 7.5 or 11KV Delta.

[@joelpritchard451]

Why is no one calling 911

[@GlennHurse]

Australia bud.. we have 000.. and the call was made before starting the recording we had to wait for the local electricity authority (Ergon)to arrive to isolate, then repair.

Over load

[@GlennHurse]

a combination of Light rain and dust from protracted dry conditions.. The fire developed in the Isolation switch from the 11kv delta to the 240v Y transformer aka 11kv to Street voltage. The moisture allowed an arc to form between phases A couple of hours later new Isolation switch and some amazed civilians
