Based on computer modeling, we have considered the effect of a spatial arrangement of wires on electromagnetic pollution of environment on high-voltage electric transmission lines. This pollution is determined based on voltages of electric and magnetic fields. We have considered two variants of the arrangement of wires on power towers. The first version provides for the location of wires in a vertical plane and the second variant provides for the location of the wire at corners of a triangle. Three modes of the high-voltage power line operation were considered: 1) normal with a load at the receiving end of the power line 120 + j90 MVA; 2) break of the phase A wire at the starting end of the power line; 3) two-phase short circuit. The simulation result in the Fazonord software package showed that the spatial arrangement of the wires significantly affects the maximum amplitudes of the electric and magnetic fields at a normalized height of 1.8 m. Moreover, the nature of dependence of the voltage on the x-axis coordinates directed perpendicular to the path of the analyzed power transmission section changes. The results of the simulation showed that under symmetrical load for a power line with a triangular arrangement of wires, the maximum value of the amplitude of the electric field show insignificant increase in comparison with high-voltage power lines with vertically arranged wires. The same indicator for the magnetic field shows increase of one and a half time.
