Flicker - Causes and Remedy [Demo]

If you observe visible light flickering (flicker), this is caused by a load fluctuating strongly in relation to the mains impedance.
powerqualityonline helps you to find causes and possible solutions.

Ultimately, these are voltage fluctuations (dips and swells) that occur in very rapid succession.
Please refer to Flicker and Voltage Fluctuations (Dips and Swells) for more details and measurement procedure.
