leading SF6 leakge detector course
Reviews: 1Estimated Reading Time: 8 minsAbnormal 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, attention would be drawn to an abnormal leak by underpressure detectors fitted to the CBs. These normally operate around 80% of normal filling pressure, and at this point in time, only 20% of the available SF6 would be in the atmosphere, leading to an SOF2concentration of 1,8 ppmv. In the case of abnormal leakage of SF6 in a medium voltage indoor substation (see figure 2 ), the SOF2 related to complete escape of SF6 from one CB would reach 17,5 ppmv. The concentration of SOF2in the switchroom at 20% relative pressure loss (commonly the alarm level) w...See more on electrical-engineering-portal[PDF]ABB High Voltage Service Gas Management Solutions library.e.abb/public/d4668a75bbb6e78585257ada00541b52...Training Training on proper SF6 gas handling procedures is essential to switchgear life extension and maintaining switchgear effectiveness.
