Asset health indices for equipment in existing substations

Working Group B3.48 was created to produce a technical brochure describing a process to classify a wide range of substation assets in terms of their changing likelihood of having an in-service failure. This would be achieved by producing guidelines for companies to build credible Asset Health Indices (AHIs). It is important to indicate realistic routes whilst pointing out pitfalls.

Substations and electrical installations

This Technical Brochure has been created by a Working Group from the CIGRE Substations and electrical installations Study Committee which is one of CIGRE's 16 domains of work.
Study Committee B3 addresses a wide range of topics that are applicable to the entire life-cycle of substation assets; from conception, through research, development, design, production, deployment, maintenance, operation, and finally, end-of life and disposal. Our activities address all stages of asset life and include not only technical aspects but also safety, economic, environmental and social aspects. All issues of performance, specification, testing, monitoring and the application of diagnostic testing techniques are within scope, with a specific focus on the impact of changing demands for substations due to continued evolution of the power system. Safety and life cycle condition assessment techniques, health indexing, risk management techniques, education and training are also important topics for our work.
