In this paper, the authors present an improved method for determining the share of harmonic distortion generated by utility and customer in a distribution system. The method is based on a Norton equivalent circuit to represent the whole system, modeling the customer side with RLC components by using measured voltage and current at the Point of Common Coupling (PCC). The proposed method evaluates the contribution of harmonic voltage and current distortion, which may appear from utility and customer sides of the system. Several case studies have been made to verify the accuracy of the method in determining the share of utility and customer harmonic distortions.
