INFLUENCE OF ENVIRONMENTAL CONDITIONS ON EMF LEVELS IN A SPAN OF OVERHEAD TRANSMISSION LINES

By O. Okun, Y. Kravchenko, and L. Korpinen

Full Article PDF (188 KB)

Abstract:
The paper is devoted to the investigation of electromagnetic field distribution in the vicinity of overhead transmission lines under different environmental conditions, taking into account the wire sag curve in a span. A wire state equation is utilized, which allows one to calculate stresses in the wire and sags based on the known stresses and temperatures in the initial state. The results of the electric and magnetic field distribution on sample 330 kV and 110 kV transmission lines are presented. We show that the highest electromagnetic field levels are associated with the most severe environmental conditions, resulting in the highest sag.
