Abstract :
The main problem for harmonic and interharmonic measurement is to reduce the effects of the spectral leakage of harmonics on interharmonic components: line frequency synchronization techniques or algorithms to compensate desynchronisation are necessary. In the paper, different proposals by the same authors are recalled and compared to each other. Numerous field measurements performed according to the IEC guidelines are reported and analysed.
