SF 6 gas monitoring and leakage detection in gas insulated

Abstract: For new installations of 500-kV gas insulated switchgear (GIS) at the Pin Hook, TN USA 500-kV Substation and the Maury, TN USA 500-kV Substation, the Tennessee Valley Authority (TVA) chose to install an advanced SF 6 gas monitoring system (GMS). This paper will discuss specifics of the GMS and how its use simplifies identification of leaking sections, facilitates planned outages for repair or replacement, and ultimately increases the availability and reliability of the equipment.
