The insulating rubber boot and the red insulating plugs can be replaced. It's not a challenging repair, but it turns a 30 minute job into days of downtime waiting for parts. We didn't have a kit on hand as we weren't expecting destruction.
Nonsparky here, mostly following for the memes. I worked in finance and entertainment, and now have a career in legal. That 3 days before the holidays bullshit is universal across all fields.
This was definitely one of the biggest worries. Thankfully it was the brass ring on the lug binding and the threads were surprisingly ok. The nut on the stud was even torqued properly.
Ya maybe you could have tried a big lag bolt/screw into the center of the plastic part of the plug. Probably would have still ended up cutting the boot. Call testing commissioning or high voltage contractors near you they may have parts on the shelf.
The boot was stuffed from just the edges of the resin as it shattered anyway, so it was always coming off. We're 1500km from the nearest distributor so our choices were limited! We are the testing/HV contractors haha
It's a connector for a medium voltage cable. Called a "dead break" because it needs to be de-energized so you can remove it with hand tools. Or in this case so it can be installed by a gorilla with hand tools and all fucked up for the next guy.
Ehh if you treat it like you would 240 or 480 then its no different. Make sure its deenergized and Greg didn't leave a pair of channel locks on it when you fire it back up.

Is this repairable ?

Running plant maintenance I'm surprised when there's not destruction.
We were only there to pop the plugs, ductor and IR the rmu and put it all back together again. None of this bullshit three days from holidays!

IT VP here. Fucking fuck Friday deployments.
Spinning in a chair right now waiting on the parts guy to show up because there's no prox where there's supposed to be one
Just dissfuckinpeared, huh? And ops is sitting around like "I dunno wah happened"
He doesn't get in until 5am and I'm graves
When the load breaks im going on break
Lefty loosey, righty also loosey
Go until it doesnt turn, then until it turns some, then go back a hair.
Did it bust the bushing also?
The bushing seems to have survived so far. We are back in a few days to repair the term, and have marked the SF6 pressure so we can monitor it.
That's some sad christmas chocolate.
Those aluminum studs like to bind.

as a layman, can some1 explain what this is? ive never seen this before.
It's a connector for a medium voltage cable. Called a "dead break" because it needs to be de-energized so you can remove it with hand tools. Or in this case so it can be installed by a gorilla with hand tools and all fucked up for the next guy.
this isn't for homes, correct? never seen anything like this.
Correct, it's power distribution. "Medium voltage" is anything from 2400V to 69kV.
damn 2400V to 69kV? f that. i hope i never see shit like this in my lifetime lol
Ehh if you treat it like you would 240 or 480 then its no different. Make sure its deenergized and Greg didn't leave a pair of channel locks on it when you fire it back up.
We use these at 35kV on the wind farms and utility scale solar.
Maybe the whole block lol
I see your hand tools and raise you my 1" drive impact
Dead Break Elbow or T-Body.
wouldn't happen with raychem ^^
True, they'd blow off themselves while powered up
Yall going to update SOP to try and prevent this again?
Typically we always carry 1 spare on whatever were doing, could also help sinching a rubber strap wrench on the tip 😉
Eww not good
Ouch !!! How did just hapen...
Do not miss doing t bodies
Doesn't look like it failed electrically, its still there. Rebuild it an go. Likely someone over torqued the stud at the test point.
