SF6 Decomposition Management

SF6 Decomposition Management

The three parameters that determine the quality — SF6 concentration, humidity and quantity of decomposition products — can now be measured in one single operation with the new SF6 Multi-Analyser. As a result, service specialists can determine on-site whether the gas still complies with the IEC Standard 60480 or whether it needs purification.

    As a contribution to the global management of SF 6, the electrical industry is also deeply involved in the setting up of strategies for the end of life of SF 6 [18]. In fact, when the SF 6 gas contains too much decomposition products, due to arc switching, the reclaiming of the gas, on site, with the help of the movable devices is not possible.

    Sep 01, 2016Sulphur hexafluoride (SF 6) is a non-toxic, odourless gas with unique electrical properties. For over 50 years, it has been used in high-voltage gas-insulated switchgear (GIS), where its excellent dielectric and arc-quenching properties make it an ideal insulating gas for medium- and high-voltage equipment. However, when the gas decomposes, it forms decomposition products that are toxic to
