SF6 Decomposition in Gas Insulated Equipment Abstract: The increasing application of SF6 as an insulating gas has led to many studies on SF6 decomposition in gas insulated equipment. In the presence of an electric arc, spark or corona, SF6 decomposes to a wide variety of chemically active products which possess completely different properties from SF6.

Abnormal LeakageInternal FaultExternal FireThe method of risk assessment is similar to that used in section "leakage from SF6 – filled equipment" which deals with normal leakage. The same case study data will be used for high and medium voltage situations. In the calculations that follow it is assumed that all of the SF6 in one circuit breaker escapes suddenly and it is again assumed that the switch room is sealed and that ventilation is inoperative.
