Really odd things occurred in my house last week. I'm not a great believer in coincidences but I can't work out what happened.
We had been out all day and on returning home found there had been a power cut for a period of about an hour. We then had four problems which definitely weren't there the day before.
1 The internet routed had failed; its PSU was OK but the electronics had failed.
2 An electromechanical timer had stopped late morning, presumably when the cut occurred. I've opened it up and the clock motor coil seems to have shorted turns.
3 A CFL in the utility room failed. Odd thing is the lamp is on a PIR, which is OK. (And it couldn't have been on with no-one in the house)
4 A 12volt modular PSU, connected to some LED strip had failed apparently with short circuit. Odd thing here is that the input was switched off, but tripped the MCB when I switched it on.
I obviously thought of power surge, but damaging items which are switched off ????
We do have solar panels, and it was sunny that day so the invertor would be going at perhaps a couple of kW at the time. Anyone know if cutting the supply in that state can create a big voltage spike or anything? No MCBs or RCDs tripped at the time. Lots of other gear in the house was running, or connected in standby mode, and is unharmed.
Any thoughts? I just don't like the coincidence option.
