abb SF6 room leakage

Jun 18, 2019In the case of abnormal leakage of SF6 in a medium voltage indoor substation (see figure 2), the SOF 2 related to complete escape of SF6 from one CB would reach 17,5 ppmv. The concentration of SOF 2 in the switchroom at 20% relative pressure loss (commonly the alarm level) would be 3.5 ppmv. HV Case studied, conditions and calculationsABB SF6 LEAK DETECTOR L-780-A ES
