MAGNETIC FIELD INDUCED BY OVERHEAD POWER TRANSMISSION LINES IN ALGERIAN NETWOORK

Abstract

This paper present simulation by COMSOL software of magnetic field at the extremely low frequency (ELF) generated in the vicinity of high voltage (HV) 60kV and extremely high voltage (EHV) 220kV and 400 kV power transmission lines in Algerian national electricity power transmission system. The influence of current loading at the magnetic field as well as the variation of towers configuration and the variation of conductors sections are treated. The experimental measurements of magnetic field near overhead power transmission lines are done by CHAUVIN ARNOUX (C.A 40 gaussmeter). The results of simulation and measurements are compared to safety limits exposures given by international commission on Non Ionizing Radiation protection (ICNIRP).
