Concepts for on-site HV testing of GIS after installation, extension, retrofit or repair

It is consensus among the members of this Working Group that performing on-site high voltage (HV) testing after installation, repair, or extension of any gas-insulated switchgear (GIS) constitutes a technically important and valuable step within the applied quality control procedures of both user and original equipment manufacturer (OEM) to ensure high reliability of the GIS for its operational life. It requires specialist knowledge and is often considered as one of the last invasive activities on every GIS compartment.

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.
