Research on Experimental Methods of Evaluating Deterioration Performance of High-Voltage Insulators

Abstract

High-voltage insulator is a kind of common and important device in the grid, in the processing of its function, effections of various environmental factors will make its insulation to deterioration and decline, without timely treatment, the accumulated deterioration may lead to surface discharge, and even surface flashover, which will damage the insulation and greatly endanger the safety of power system. A method by accurately testing the ultraviolet intensity of insulators which is under the conditions of different deterioration and filthy is proposed on this basis, and depend on which we can provide evidences for finding early deterioration of insulators.
