Most likely primary side (6-7kV) fuse cutout open. Affects small number of customers. Unfortunately requires a lineman to replace and/or clear fault.
Thank goodness for reclosers (circuit breaker-like overcurrent devices)! The power in rural areas is much more reliable because of them as things like a tree branch, squirrel, snake, etc. causing a fault that would wipe out a fuse get cleared automatically. A persistent fault (wire down, tree on line, etc.) will trip it out and send a signal for crew dispatch of course. If your power goes out, comes back on for a bit and goes off again in cyclical fashion approx 3 times then stays off that's a recloser in action.
They don't protect individual home feeds, however so the fuse opens on your particular pole pig it's gonna be out until you see a bucket truck.
I was awoken around 01:24 this AM by alarms and pointed the PTZ in the usual direction and saw green flashes every time the UPS engaged. There's a section of road to our north that has lots of tree branches near a single 6kV overhead and every time it rains hard this has been happening. Fortunately they are small enough to burn off and NOT trip the line off but it causes noticeable anomalies that our UPS' take action on. Sometimes bigger limbs do cause faults on that run and trip that line out but we have isolation switches in several places (along with 3 phases) so our power comes back relatively quickly. Far cry from what it was 40 years ago.
Barely half an inch from those storms, no wind, and some DEEP rumbles as the lightning seemed to pick up once the initial part passed to our east. At least we got some nice cooler weather ahead! Wish it would last longer though.
