Erratic Utility Voltage and Frequency Supply


Carl

Recommended Posts

I noticed that my inverter was battling to synchronize to the grid after load shedding yesterday afternoon

 

The supply voltage was very low at 202 Volts ac and the frequency was 49.8 Hz.

 

Are there any major problems associated with this erratic supply?

 

Premature failure of appliances, overheating of cables and appliances, clocks slowing down etc?

That voltage is very low.  It might cause especially motors (fridge compressors etc.) to run hotter than normal.

 

Most (cheaper) clock radios and also some microwave ovens and some stoves use the 50Hz mains frequency for their clock source.  If the mains frequency drops e.g. when ESKOM is under strain, these clocks do run slow.
