What causes poor power quality?
Voltage fluctuations are generally caused by loose or corroded connections at either the house or on the power lines, and are often noticed by flickering lights. Dim lights can be a symptom of the voltage being too low. This can be caused by overloading on the network, loose connections or the conductor wire carrying power to your house being too small. In extreme cases, a loose connection can cause electric shocks from metal appliances and surfaces in your house. Power surges and spikes are commonly caused by lightening, power switching on the lines or sometimes from household appliances drawing excessive amounts of power in either your own house or neighbouring premises. Other less common causes of power surges and spikes include lines clashing as a result of trees, strong winds, vehicle accidents or possums and birds on the lines.
