Thisresearch study makes an effort to
evaluate the harmonic distortion in the distribution systems caused by the various non-linear residential loads. The
experimentally developed harmonic spectrums, of several home appliances, are deployed for the simulation of a
typical UK distribution system using Electrical Transient Analyzer Program (ETAP). The results show high level of
harmonic distortion, at the Point of Common Coupling (PCC), in the distribution system which becomes even more
aggravated when a higher loading level, of the distribution transformer, is considered
