Why electricity boards need to pay us for damaging our fridges, TVs, A/Cs
Many of us have had our fridges, A/Cs and TVs damaged because of power problems
Replacement of equipment is often the only option when this happens
We think damage happened because of voltage surge but things are more complex
Power is supposed to be of certain voltage, current and frequency
Sudden high current can happen if there is an earth fault somewhere in power system
Beyond this there is something called power quality
For instance, electric chargers used for e-vehicles can pollute the power lines by injecting “harmonics”
Solar power has unhealthy components that can affect equipment
For instance, the MRI’s or EEG’s diagnostic ability may be affected
Our electricity boards are required to ensure good quality power is supplied
If they don’t, they are liable to pay for damage that polluted power can cause to our equipment
Regulations cover power quality besides limits on voltage and other fluctuations
