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