Voltage Fluctuation. , including voltage flicker, means a rapid voltage change in fundamental frequency voltages over several cycles. The rapid voltage changes could also be in the form of cyclic changes (voltage flicker). Note: Voltage Fluctuations are normally caused by start-ups, inrush currents or switching operations of equipment.
