The use of power electronics systems has increased over the last few years. Because of that, there is a crescent problem about current and voltage waveforms distortions. This paper deals with the study of 3rd order harmonical filters, presenting alternatives to the use of isolating transformers. The application of filters, results in the attenuation of the problems causeds by the harmonical distortions, this fact does the durability of the equipments and the energetic efficiency increase. In the course of the text, there are the most famous topologies for passive filters for attenuation of harmonical distortions on the waveforms and simulations by the tool Simulink of MatLab. In order to do this study, an industrial installation with common parameters was modelled. Besides offering to the low voltage consumer a viable action against the waveform distortions, this paper has the purpose of make the society aware of this increasing problem that is lack of legislation on Brazil.
