sulfur hexafluoride storage pressure in substations
Due to the above reasons, SF6 is used mostly in applications that allow reclamation as opposed to using it on equipment that requires release of the gas, only to be re filled with virgin SF6. ENERVAC produces a complete line of SF6 recovery and test equipment, from full sized gas reclaimers down to small decomposition detectors.

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, 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 portalReviews: 1Estimated Reading Time: 8 mins[PDF]SF Measurement Solutions 6 GAE gae.id/userdata/uploads/pdf/SF6_Leak_Detector_3434i...TheLumaSenseSFLeakDetectormeetsallofthese 6requirements.Inaddition,themonitorcanoperateunattendedforlongperiodsoftimeallowingourcustomerstofocustheirmanpoweronotherkeytasks.ThemonitorcanalsobecombinedwithanINNOVA1309MultipointSamplertoenablebroadareacoverage.
