Abstract

Second order harmonic components, and in general even harmonics, produce asymmetries in voltage and current waveforms that can lead to undesirable effects on power system loads. Until now, the level of the second order voltage harmonic has not been investigated in depth in power systems. This paper reports the results of the monitoring of second order voltage harmonic group and subgroup, as defined in IEC harmonic measurement standards, in a low-voltage distribution systems and the effect on the asymmetry in voltage waveforms
