• Flicker (376)

Flicker is the impression of unsteadiness of visual sensation induced by cyclic variation in the intensity or spectral content of a light source due to fluctuation of the supply voltage. It does not have any important effect on equipment, but it affects the concentration and productivity of people. Since flicker is a voltage disturbance, it affects neighbouring consumers and is one of the biggest causes of customer complaints. This Application Note introduces flicker and discusses the causes and available mitigation measures.
