This isn't strictly c-bus but... I suffer from a pretty noisy electricity supply. The lights regularly (but not frequently) dim momentarily. Some CFLs go out and do not fully re-light on a bad fluctuation. Anyway, my fridge / freezer (large domestic 2 door model) seems to run a lot. You can hear a the tone of the compressor / fan running change just slightly if a fluctuation occurs whilst the compressor / fan is running. The funny thing is that the fridge seems to run a lot and it seems to run more on a night when we have power fluctuations. Could it be that power fluctuations cause the fridge to run more than it should? I'd appreciate any thoughts / insights. Also, any advice on dealing with the electricity supplier to get the fluctuations dealt with (Melbourne metro) or, any devices I could install to improve the electricity supply. Thanks in advance.
