If you can find someone who has recently had some electrical supply work done then they may have a map of your local distribution grid. Worth finding a copy (or talk to your local PC they may have one).
That is much more likely - they haven't done preventative tree maintenance here since they took over from NEDL (who did it every 2 years). One of our failures was a tree fell onto a major line, the other was a pole thinned to 3" that snapped at cow rubbing height.
I agree that we have had more than our fair share of outages this autumn. It wasn't such a problem in the past. They seem to coincide with high rainfall where I am which could be weighing down tree branches.
We used to have 240 volts on three vertically arranged once insulated with fabric and rubber lines. The rubber had long since perished and strips would hang down between the lines. In the wind and wet they would arc and spark spectacularly dropping bits of burning rubber onto the ground. It would dim the lights sometimes but arcs never persisted for long enough to trip out a higher level breaker.
Also ask farmers if they have the power grid distribution map for their property. I suspect if you stay off when others are reconnected it is usually because the hard fault is on your patch.
We have mapped our entire zone and know where all the substations, transformers, switched and breakers are for next time.
There are usually two at least where we are. Here there is full 3 phase running N-S on bigger poles that have a t shape at the top ie. . _|_. | |
And spurs off that that just have the two lines. I hadn't realised that my part of the village only had two phases until we investigated exactly what was going on during the long storm Arwen power cut.
