Abstract

This paper is an analysis of electric-fields distribution around overhead transmission lines (OHTLs) with an all dielectric self supporting (ADSS) fiber-optic cable. The aim of this analysis is to determine electrical interactions on a fully dielectric cable located in the electric field of OHTL. Two characteristic areas were taken into consideration. The first of these-in the middle of the line span, and the second-around the clamps which fit the cable to the transmission line tower. These areas follow from localization of ADSS-type cable in the line span. The latter of this area was taken into detailed analysis for determining the conditions of electric discharge initialization on the cable's surface.
