Resumo

With the advance and frequent use of electronics devices, unwanted phenomenal have emerged in the Electrical Power Systems related to Power Quality. Faced with these events, new studies have appeared, dealing with the effects caused by harmonic distortions. In this scenario, this paper aims to apply the Conservative Power Theory to assign responsibilities due to harmonic distortions in an electrical system composed of linear and nonlinear loads for four consumers. For this assignment, will be used the Harmonic Current Generated by the Load Method to analyze four specific cases with the presence and absence of harmonic distortions.
