Yesterday morning we had a brief power cut - nothing too unusual about that. Following the restoration of power though, the voltage was dipping up and down. The UPS (Uninterruptible Power Supply0 that keeps my desktop computer running through a power cut kept switching to battery as the voltage dropped below the preset level.
It seemed to settle down during the day but then at night the problem returned. LED lights don't seem to be effected by changes in voltage but the halogen bulbs in the kitchen are. They were dimming and brightening constantly for well over an hour.
Things settled down again and I hoped the problem had been resolved but no. This morning, the power cut out again for a short while followed by more variations in the voltage. Is it the weather that is causing these problems, I don't know. I do know it is a pain in the butt!
