The present article has as the aim to analyze the level of harmonic distortion of voltage in the bus in an electric system in the presence of evaporative refrigerators used for the cooling of environments operated by converters of frequency in which measurement campaigns were carried out in field. Considering that the frequency converters with the filters absence make the system presents nonlinear characteristics whose analyses are of great matter in what concerns about the quality of the

In this context, through computational simulations, there was observed the efficiency of the passive filters tuned with objective to reduce the levels of harmonic distortions of voltage in the bus in study and to adapt these levels to the standards of reference contained in the existing resolutions. 1
