Overview of Non Intrusive Methods for Switchgear Condition Assessment prepared by CIGRE/CIRED A3.32 Working Group

Abstract

This paper presents an overview of Non-Intrusive Condition Assessment that can be applied on HV and MV circuit switchgear. Many emerging non-intrusive techniques are reported in the literature, most of them allowing in service evaluation. The CIGRE/CIRED Joint Working Group A3.32 reviewed the current and future trends of non-intrusive, especially in service, diagnostic methods completing the work on Condition Assessment of Switchgears. This can be valuable information for anyone who is going to apply or improve Condition Assessment Methods to Switchgears.
