RESUMO

Harmonics distortions are one of the more common questions in the electric systems. This research proposes a new alternative to attenuate zero-sequence-harmonic injection by using an electromagnetic filter. This document identifies the functional principles of the electromagnetic filter for zero-sequence-harmonics, establishing a representative mathematical model of its electromagnetic arrangements based on reluctances and magnetomotriz forces. It presents, also, a model of the studied device in a computational base using time-domain. Finally, laboratory and computational tests for evaluation filterâs performance had been carried through.
