Discuss various causes of voltage flicker?
Answers
Voltage fluctuations are systemic variations of the voltage envelope or random voltage changes, the magnitude of which does not normally exceed specified voltage ranges
Flickers may occur at any time – even on a sunny day – and can be caused by a number of factors, including: Lightning strikes (Florida is the lightning capital of the nation) Damaged electrical equipment. Vegetation – tree branches, palm fronds or other debris – making contact with power lines.
Loose or corroded connections either at the house or on the powerlines can cause voltage fluctuations. This is often seen as flickering lights. Low voltage due to overloading on the network, loose connections, or too small a conductor wire carrying power to your house may cause dimming of your lights.
