Mitigation of the Electromagnetic Pollution Inside El-CHAFIA High- Voltage Substation (400KV)

EasyChair Preprint 15896

Abstract

The regulatory update concerning occupational and public low frequency exposure published by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) in 2010 is widely recognized and formed the basis for national regulations in Algeria; this requires verification of compliance with the deriving recommendation. In this paper, the assessment of low frequency professional exposure inside EL CHEFIA 400 kV substation belonging to the Algerian SONALGAZ company is investigated. An analytical characterization of the electromagnetic environment beneath a selected circuit of 400 kV power lines inside the substation often requiring maintenance is outlined.in the second part of the paper , the programs developed based on Matlab software provide a solution for the analysis and reduction of the electric field intensities for highest ground clearance levels close to the towers ,in order to predict live –line- workers safety . General conclusions arising from the comparison of the results with the IEEE and ICNIRP standard levels for occupational exposures as well as recommendations to ensure workers safety are finally given.

Keyphrases: Low frequency occupational exposure, Passive shielding, high voltage transmission line, standard limits
