Operation and Maintenance of a Gas Insulated Substation

This course gives real life experiences from existing GIS technology that has been in service for a number of years. It describes the nature and sources of defects including their repair and sophisticated planning. Usual maintenance methodologies on measures to determine the quality of the SF6 insulating gas, visual and optical verifications, gas handling records, and leak detection routines are presented. Special practices on interlocks, gas zones, spare parts, and special equipment are discussed. Experiences and lessons learned on gas zone identification, secondary interface, wiring methods are combined and presented. Preconstruction staff training that involves continuous monitoring, GIS retrofit and bus leak maintenance topics are also discussed.
