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. (see figure 1). In practice, atte…See more on electrical engineering portalOperation and Maintenance of a Gas Insulated Substation cedengineering/userfiles/Operation and Maintenance of a...PDF fileOperation and Maintenance of a Gas Insulated Substation Course No: E04 044 Credit: 4 PDH Velimir Lackovic, Char.
