With the fault being on the secondary side of the transformer, there is not enough fault current to blow the primary side fuses, and therefore, nothing upstream is going to care either. Now, let that fault carry to the 12kV side, and things will start to clear that fault pretty quickly.
Unless those cartridge fuses blow on the Primary (12KVA) side, the transmission lines will reset a few times before the (intelligent) breakers finally trip into a fault position. It's why the Primary transmission lines, when they go down and hit the ground, are so bloody deadly. Stay away from them.
And loaded with nasty toxins (PCBs?). A guy near here years ago was somehow collecting them to get the wire out of them I guess, and was just dumping the oil on a hill above a lake. You couldn't eat the fish out of there for years.
I worked my way through college in the 70s for the phone company. This is not telephone but electrical as the telephone is lower on the pole. The electrical is sparking out of the arrestor/cutout from the transformer when there is an issue with the electrical.
It’s not hitting on all 8.
ReplyDeleteWhen these go up at night it is rather spectacular, like a massive lightning storm.

ReplyDeleteThat boy ought to move his Snap On truck.
ReplyDeleteIf he doesn't the damages could be in the billions.
DeleteHope the truck is not electric!

ReplyDeleteIt's an electric car backfiring ... Needs the valve timing adjusted to fix it.

Had one of those explode on our Wisconsin dairy farm. Spewed oil all over the "yard". Who knew that they were cooled by oil in that big can?
