A computing approach to risk assessment related to electromagnetic field exposure from overhead power lines

Abstract

The paper presents a computing approach to risk assessment of the occupational exposure of persons to electromagnetic fields from overhead power lines. With a computer program, created by the authors, data for the electric field intensity at a point on arbitrary height from the ground, transversely from the center of the tower of the transmission lines 110 kV, 220 kV and 400 kV, are presented. The current flowing through the person, located in the area of the point, and the power absorbed by the body are also obtained. The calculations are done for different types of electrical power line towers as a construction and as an arrangement of the phase conductors. The employers may assess the risks of exposure to electromagnetic fields at the workplaces based on the data presented in the paper for many typical towers of the transmission lines.
