This is due to the use of electronic equipment that the prisoner is not liniear, high levels of distortion very influential in the performance of the transformer. The effect of harmonising on transformer raising loss ? transformer losses that would later lead to a reduction of capable power transformer that would harm the electrical company. So in this thesis was carried out data retrieval in the distribution station B 109 type of concrete with the capacity of Transformer 630 kVa, with reference to the standard of a SPLN D3 ? 2007. From the results of calculations for 7 days obtained Total Harmonic Distortion (THD) voltage ranging from 0,667014 % to 0,912153 %, and Total Harmonic Distortion (THD) currents ranged from 9,119792 % to 12,06458 %. The impact of the distortion experienced decreased power can range between 0,99 % up to 1,65 %. By using a single tuned passive filter on the order of 3 distortion decreased the current of the THD from 10,9903 % to 1,401 %.} }
