Abstract :
The paper describes the measurement procedure for calibration of power quality parameters. Procedure uses the asynchronous sampling technique with multi harmonic sine fit algorithm to separately determine harmonics, interharmonics, fluctuating harmonics and flickers. It gives small enough uncertainties to cover calibrations of all commercially available power quality sources and meters.
