Abstract :
This paper studies the effect of the Hanning window (HW) on the processing of harmonics and interharmonics in the framework of the standard defined by the IEC. The performance of the HW is studied both in the processing of a large harmonic current fluctuation and when an interharmonic voltage component appears between two contiguous harmonic components. The results obtained are compared with the results obtained when applying the method defined in the standard and the root mean square value of each signal.
