Tools for lifecycle management of T&D switchgear based on data from condition monitoring

The Technical Brochure of WG A3.43 focuses on transmission and distribution switchgear across various technologies, with the primary objective of developing a comprehensive method for assessing switchgear condition, addressing mechanical, dielectric, electrical wear, and auxiliary circuit degradation aspects. By identifying suitable parameters for evaluation of each functional aspect, the initial aim is to establish guidelines for qualitative and quantitative assessment. Further, it provides an overview of reliability assessment methods used for other substation assets and recommendations for alignment of results. The goal is to provide a universally applicable quantitative approach, independent of technology, to assess the health condition of switchgear.
