The progressive use of power electronic devices, connected to the electrical system, has contributed to the increase of problems caused by harmonic disturbances in electrical networks. Thus, this work aims to develop a methodology to analyze the harmonic impacts on the electrical grids caused by non-linear loads with the use of the Decision Tree technique. The model used was the regression tree through the use of the Classification and Regression Tree (CART) algorithm, which relates the harmonic current of a non-linear load and the harmonic voltage at the common connection point of the electrical grid. The technique used was applied in a case study in order to show the validity of its application in solving problems that seek to investigate the dependency relationship between the two variables. Among the feeders used in the research for the 3rd harmonic analysis, feeder DIAL2-19 contributed the impact factor for phase A with 43.587%. The feeder DIAL2-16 contributed with impact factor 36.407% for phase B. For phase C feeder DIAL2-17 contributed 26.434% impact factor.
