While restoring service to a side line , topside of cutout did not make good contact . Was only burning for a few seconds , but even after opening the cutout continued to melt for another 5 minutes after opening

Interesting to see the cutout jumpers moving with AC vibration during the bad contact with the fuse door closed. Thanks for sharing! As known, these systems are pretty inanimate during normal operation. I find it interesting to see how the effects of controlled electricity in a fault condition (in any form of fault) reacts with the infrastructure environment where the fault is and chain reactions down-Load/up-Line.
Yesssss great comment! It's definitely wild how a fault can violently throw a jumper around like a ghost. It's just like how muscles in one's body will contract tightly as current flow increases when the voltage is high enough to exceed their natural resistance.
It's definitely a "force" that is to be respected
@@Bobsdecline Electromagnetism, it not only makes our lives interesting, it *makes* our lives. xD
Were they really moving because of the current? i mean, i know it is possible, but i don't think that would happen in this structures, they weight too much, they require a lot of energy, also, i think that the frequency is too high for it to be noticeable... and even if it were possible, won't they be vibrating the whole time?
@@rhodexa Ya the line frequency is 60hz. The wires are vibrating pretty slow. To me it looks like there vibrating from the cutout shaking.
mmmm ... 60Hz and plasma arcing is enough to vibrate and melt anything given enough time and heat involved.
Viscious and unforgiven if left unchecked.
Electromotive force.
It's so pretty.
I’d love to see that in slow motion
Did that loadbreak cutout get replaced afterward? In my area standard porcelain versions have been falling to pieces, just saw it again on a transformer pole
Yeah, we changed it right away. There's a specific model of porcelain cutout that was really bad, so we removed all of them from our system. We then moved on to major structures, tx banks, main lines. Now we are getting to all the single phase lines and transformers
It scares me.
Was the load break bent and not letting it go in all the way?
Clint Ferguson wasn't bent , but looks like top hood may been been damaged when fuse blew earlier in the day ... Was hard to tell tho how much of the pitting was from before or after that arc. After removing it and getting a closer look , it still didn't seem to be that bad and was only picking up about 20 amps !
That cutout very literaly cut out lol
