Abstract

Several voltage unbalance conditions produce different harmful effects to the proper functioning of the many electrical system equipments, such as three phase induction motors. Thus, it is essential to know those responsible for the unbalance, on the one hand the energy distributor having a duty to provide a supply in accordance with the regulations and, on the other hand, the consumer who wishes to receive energy with quality and is obliged to maintain its installation according to the norms. In this scenario, the present paper has as objective to evaluate the conforming and non-conforming current method in front of an electric system with the presence of unbalanced loads and a three-phase induction motor with regard to the attribution of responsibility due to voltage unbalance.
