Operation and Maintenance of a Gas Insulated Substation
Author: Velimir Lackovic
This course presents several 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 maintenance. It covers routine measurement methods to determine the quality of the SF6 insulating gas, visual and optical verifications, gas handling records, and leak detection routines. This course also reviews special practices on interlocks, gas zones, spare parts, and special equipment are discussed. Experiences and lessons learned on gas zone identification, secondary interface, and wiring methods. A discussion on preconstruction staff training for continuous monitoring, GIS retrofit and bus leak maintenance topics is included.
This course is suitable for engineers with a desire to understand the fundamentals of GIS technology operation and maintenance. It combines theory with real life experiences and presents methods and strategies that have been successfully used for a number of years. Upon successful completion engineers will be able to address GIS operation and maintenance terms, cause of the defect and methods to fix and mitigate them.
Once you complete your course review, you need to take a multiple-choice quiz consisting of thirty (30) questions to earn 6 PDH credits.
