And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.
Yeah. Like dead. Anything over 220 ist nicht fur die fingergepokin by das dummkopfs. Which includes a fair number of electricians and pretty much all machine operators.
I went to a tree service safety seminar in the mid 80's. One of the classes was electrical safety. Residential electrical high tension lines are around 7 kv. That will arc across 3 to 6 feet to ground out on you or your pole pruner or bucket truck or whatever else you get too close with, UNLESS it's certified non conducting. The class had 2 real power poles, wires, set up, complete, with a trash can size, residential transformer, PLUGGED into the 110v wall outlet! The teacher's aid was a wooden pole, with a grounded spike on the end. He put a sausage on the spike. Then he put the spiked sausage into a certified, 10,000 kv proof glove, with a pin hole in the finger. Then he approached the wire. Got within about 3 feet and BAM!!! Huge, BRITE, flash and boom! He involuntarily, reactively jerked away instantly. Sausage was burnt black that fast. My respect for magic, angry electrons went sky high from then on.
There are a number of videos on You Tube that show what can happen at the stinger. One showed a bird standing on the xfrmr and a bolt came from the line and the bird vaporized. There are a number that show squirrels getting fried as well.
looks like he was pulling the charge handle to tension the spring that when released, closes the actual contacts? Did it release prematurely? That's what I'm thinking. It's been about 30 years since I worked around HV switchgear, and that was 26 kV, dropped down to 4160 for plant distribution.
could have been much worse

ReplyDeleteWhen I was in the Navy, there were two ratings that dominated the obits from the fleet, Electricians and Electronics Technicians.
DeleteDad ist korrect! But some bright spark out there wants soccer moms to charge their EV SUVs at 800 volts. That’ll put a curl in their perms
DeleteStupid substation electrician , get a disposable lineman.
ReplyDeleteWith that much energy available seems like a good place for total arc/flash protective protection.
ReplyDeleteSome of the lettering looks Cyrillic. Might be standard Russian percussive maintenance.
ReplyDeleteIt is Cyrillic. May not be Russian, though.
Deletelooks like a switchblock crossed out on him when he pulled the switch lever
ReplyDeleteI have video of a guy working on a box in the rain......
ReplyDeleteIt exploded.........

hey, just the inductance will kill you when its at those voltages

Deleteit's not the volts that kill you it's the amps. Sheet, I get hit with a few thousand volts just taking off my sweater.
ReplyDeleteThat’s true to some extent but what kills the unwary is the arc flash that can burn you to the bone. You die of third degree burns
DeleteRacking in the bucket on a HV breaker. They do that sometimes.
ReplyDeleteHigh voltage. A very effective Darwinian filter.
