Abstract. The aim of this paper is to apply a methodology towards the sharing of responsibility between the utility and the consumer with reference to the occurrence of harmonic voltage distortions at the point of common coupling (PCC). The approach is based on the measured values of harmonic voltage and current as well as the supply and load harmonic impedance information. In addition to the general method principles, the paper focuses a specific application involving a real industrial installation, fed by 230 kV and having a large amount of rectifiers. The results are then used to verify the proposal consistency regarding the sharing of the responsibilities between the utility and the industry as far as the harmonic voltage distortion is concerned. The proposed process finds sustenance during the implementation of mitigation procedures with sights to the attendance of the standards of quality established by the regulating agencies. Key word
