Abstract

This paper presents a measurement technique to determine the harmonic sources and impedances of residential houses at the utility metering point. The results are then applied to quantify harmonic and current contributions of the residential premises. Four residential houses are investigated by using the proposed method. The characteristics of the load-side harmonic impedances and sources are studied, and their harmonic contributions are determined. The results show that voltage distortion is affected mainly by background harmonic sources that exist within the supply system. The current harmonics are affected by the residential loads and the supply system.
