#recloser
I'm a bit of an expert in protection engineering, so I guess I should be fired and the garbage man should start developing recloser settings. I'm sure that'll end with no additional deaths or forest fires.

And in the meantime I'll start driving the garbage truck.

haha quick 2 second power outage followed by the delayed pop of a recloser operating way off in the distance

Hot take here, if you don't know the importance of voltage management or fuse recloser coordination you probably should be measured about grid edge resilience too if you're arguing for greater renewable penetration
"grids need to adapt to a more decentralised, digitalised and flexible electricity system with millions of rooftop solar panels and local energy communities sharing resources." = reliability and resiliency will possibly come from the grid-edge 🤷‍♂️

Pad mounted remote operated switch gear. Is it a recloser or just a remote isolation switch?

*possible* but I would assume a recloser/fuse would pop by that point. Protection is designed to trip out in case of flickering like that normally.

That's basically to stop a circuit breaker or recloser from closing in on a circuit that's still energized but not synchronized. Closing in out of phase is bad news, and the even worse bit is that in a situation of inverters vs the big grid, the big grid wins and your inverter fries.

when your power goes out and you hear a bang, its almost never a transformer blowing up. its either a fuse cutout blowing (if it stays out) or a recloser temporarily interrupting the power when a fault is detected and turning it back on)

both are very loud

i was so stupid back then, this is a recloser
owo?

*opens your motor operated line disconnect*

TIL about "unintentional islanding": scary stuff!

TL;DR: subcircuits stay energized (e.g. by distributed PV) when the utility opens a recloser, unbeknownst to the them, endangering workers and the general public 😬

slowly failing insulator, no immediate concern, will just trip out a fuse/recloser upstream at some point. If the noise becomes disruptive, contact the utility; they won't approve replacement until they have documented customer complaints first.

The local volt var control also says nothing about if the protection systems and fuse recloser coordinations are safe and these are a major *must have* in the operation of the system. Just as much as the voltage and thermals

Worst I’ve seen was a line sitting on snow. Pulls some amps but not enough to trip the recloser. And if it’s an ungrounded system there’s no good path to substation neutral, which makes it even worse.

my talking-out-of-my-ass guess is that there was a transient fault somewhere on the grid that either resolved itself or was routed around. for example, a recloser is basically like the circuit breaker in your house, but for the power company, and it resets itself after it trips:
