Abstract—Voltage fluctuations caused by rapidly changing
loads in the power systems may give rise to noticeable illumination
flickers of lighting equipment. The voltage flickers can also cause
malfunctions in many electric devices. This paper presents a digital
implementation of flickermeter in the hybrid time and frequency
domains based on IEC Standard 61000-4-15. In addition, this
paper proposes a new demodulation method to extract the voltage
envelope. Simulations and actual measurements show that the
digital implementation with the proposed method yields relatively
accurate flicker measurements.
