Monitoring of electromagnetic pollution inside switchyard substation : case study : El-Hadjar electrical post in Annaba City, Algeria

الملخص EN

The aim of this paper is to carried out an experimental characterization of the electromagnetic environment beneath a selected circuit of two 220Kv power lines inside El- Hadjar electrical post often requiring maintenance.

An analytical calculus method is proposed in order to accomplish this study.

The model of the circuit of lines proposed was constructed using the actual physical dimensions of the towers.

It follows a numerical simulation of the field’s magnitudes for highest ground clearance levels close to the towers.

General conclusions arising from the comparison of the results with relevant reference levels in force for occupational exposure as well as recommendations to ensure workers safety are finally given
