The quality of the SF 6 gas must be analysed, since it can lead to chemical reactions in the gas when used in gas-insulated switchgear, due to the high energy occurring there. An analysis of the SF 6 gas quality is always recommended and should be an integral part of the maintenance strategy, especially before any gas handling.
