Abstract :
Calibrated harmonic analysers are required to underpin international regulations regarding harmonic emissions for electrical appliances. A method to accurately analyse waveforms containing smoothly fluctuating harmonics is described. The response of an analyser to the characterised waveform is considered and a method to calibrate an analyser is presented
