High-voltage Equipment State Assessment Method Based on the Integrated Use of Advanced Non-Destructive Technologies

Abstract

This paper is devoted to the results of the study on assessing the efficiency of additional methods for the technical diagnosis of high-voltage equipment in power stations and substations. The efficiency of thermal imaging, ultraviolet testing and the method of monitoring partial discharges in isolation was analyzed in this study both individually and together. The study subject was the methods of diagnosing the state of high-voltage electrical equipment which implied the development of a theory in the field of integrated assessment of the technical state based on analyzing the performance indices of high-voltage equipment.
