Just looking for some advice.
I bought a UPS to protect a computer from occasional outages. It has been going to battery despite there being no power problems. After speaking to the manufacturer it seems the problem is one of high voltage input. Here's a nice graph I made from the readings of the UPS. Resolution is 2 seconds, so it's about 2 hours or so.
How do I go about working out what the cause of the high voltage spikes are. The UPS has a default shutdown of 266 volts and you can see on the graph that there are quite a few spikes of that magnitude.
I literally have no idea where to start with this one. Funnily enough I had a sparky come visit today (install some sockets). He didn't mention noticing anything dodgy. I hadn't got this far then, so didn't ask him about this at the time.
If the problem is in the house, what are the likely candidates?
