Global Anthropogenic Non-CO2 Greenhouse Gas …

SF6 emissions from electrical equipment used in transmission and distribution systems occur through leakage and handling losses. Leakage losses can occur at gasket seals, flanges, and threaded fittings, and are generally larger in older equipment. Handling emissions occur when equipment is opened for servicing, SF6 gas analysis, or disposal.

1 High-Voltage Switchgear Installations - academia.edu

SF6 gas for switchgear must be technically clean and comply with IEC 60376. Gas returned from SF6 installations and apparatus is dealt with in IEC 60480. SF6 released into the atmosphere is a greenhouse gas with a very high potential effect.

2.2.12 Gas Monitor System The insulating and interrupting capability of the SF6 gas depends on the density of the SF6 gas being at a minimum level established by design tests. The pressure of the SF6 gas varies with temperature, so a mechanical temperature-compensated pressure switch is used to monitor the equivalent of gas density (Figure 2.14).
