ECN Forum Forums General Topics of the Trade Non-US Electrical Systems & Trades Faults Calls

Is there an explanation to go with that picture? Any idea where this was, or what level of HV was involved?

I don't remember the details. It was posted at powerlineman.com a couple of years ago. I believe it was at a US utility—maybe 34.5kV [19.9kv to ground.]

The webmaster there mentions that due to disk-space limits he only keeps images for about a year.

Bjarney,
Thank you very much!.
I take it by this you mean, a system like Merz-Price(?) HV protection?.
When I was being trained up for Faults work, I was warned to keep my feet together, if I suspected that there may be a HV ground Fault, nearby, this was brought back to me recently, when I was training up a new Liney as a faultsman and he was leaping around(with his feet together) at a callout we were doing one night, I asked him why and he said, in case there was an Earth Fault!.
(Better to be safe than sorry, I suppose)

I posted a topic related to this a while back, but I went to a Faults callout this afternoon, a broken pole.
Of all the poles on the road in question, they had to hit the one with the Xformer on it.
33kV lines and a 50kVA tranny on it.
Luke(new Faults guy) and I got there and the Fire Crews were at work, as were the Ambulance people.
Went w/ Luke to pull the ABS at each end of the ring.
Oddly enough, none of the DDO fuses dropped, even though the pole top was lying on the ground.
First time I ever saw this as a FF, it scared the Hell out of me, you don't have street-lights out in the country.
