Since the thunderstorm, the electricity in my house has been stable. Today though, it has started fluctuating again. The symptoms are the same each time it happens.
- The halogen lights in the kitchen fluctuate between dim and bright.
- The central heating boiler comes on for a brief second even when the heating is switched off.
- The UPS that is the backup battery for my desktop computer signals a drop in voltage below the threshold that is set.
