Abstract

The paper presents a study into the potentials and electric field distribution on insulator strings, which are used for suspension of overhead transmission lines of 400 kV and are stressed by power frequency voltage. The investigated insulator strings are used by the Public Power Corporation of Greece in high voltage transmission networks. The finite element analysis (FEA) program OPERA was used to carry out the electric analysis on the insulators. Two types of insulator strings were investigated, the first using porcelain and the second using glass as the insulating material. A comparative analysis of these insulators is presented
