Investigation of electromagnetic interference due to high voltage line

摘要

The interference from high voltage (HV) lines to human beings, vehicles, telecommunication cables, buried pipeline and closely located metallic structures has been a topic of interest over the past 25 years. Interference from HV lines may be electrostatic and electromagnetic interference. Now a day, public are extremely fretful about the effects of HV transmission lines on their health. Probable risk for leukemia, neuropsychological disorders, breast cancer, and reproductive outcomes has been reported due to this exposure. The present work refers to these aspects, trying to systematize the knowledge for evaluation of the electric field distribution of the three-phase conductors. In this work, two case studies are investigated. The analytical calculus and simulation of the electric field distribution of HV overhead lines has been analyzed. In the case 1, the 11kV HV line is analyzed. The analytical calculus is done by MATLAB and simulation by COMSOL MULTIPHYSICS software. In the case 2, two types of 230kV structures are analyzed and the best phase arrangement for reducing the electric field is determined (the circular arrangement). It is concluded that the circular arrangement of conductor is to reduce radiations.
