The results of simulation tests concerning the cooperation of the nonlinear load with the power system are presented. In numerical experiments we have taken data from the real systems, including the cable and overhead lines. In practice the nonlinear load of high power may be supplied by the overhead or cable lines. The paper presents the comparative analysis, how the applied type of the line influences the level of distortion of the voltages and currents in the power system. The values of the higher harmonics of the voltages and currents as well as THD have been determined in the paper. These values have been estimated for the beginning and ending terminals of the overhead and cable lines supplying the nonlinear load of the inductive character concerning the cooperation of the filtering compensating device and the nonlinear load of high power. All experiments have been performed using MicroCap-8 program. In the paper we have included he exemplary results of the numerical calculations.
