Impact on Engineering and Lifetime Management of Outdoor HV GIS

GIS has been used as an effective solution for the design and operation of substations since the 1960s due to its excellent features such as compactness, encapsulated components, resistance to environmental pollution and increased personnel safety due to minimal exposed high voltage components. The majority of recently constructed GIS installations are indoor, particularly in Europe and North America, but GIS applications using an outdoor design are numerous throughout the world, particularly in Asia and the Pacific Rim.

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.
