Oct 23, 2020Although for both interruption and insulation, sf6-gas gas is used in many medium voltage GIS system. But for such equipments rated sf6-gas gas pressures are different for interruption and insulation. sf 6 gas pressure for insulating purpose is generally kept below 2.5 bar whereas sf 6 gas pressure for interrupting purpose is ranged from 5 bar to 7 bar.
