The Calibration of IEC Standard Flickermeters Using Complex Modulated Signals

Flickermeter calibrations currently rely on the predicted response of a standard flickermeter to basic waveforms. A description is given of an interpretation and implementation of the IEC standard flickermeter, developed at the national physical laboratory (NPL), to assess the response of commercial flickermeters to more complex waveforms, which are representative of signals that occur in practice. A description of the incorporation of the resulting model into a calibration system for flickermeters under complex-waveform conditions is given.
