  • SF 6 gas insulated switchgear check for leaks detecting

    sf6 gas gas insulated switchgear check for leaks detecting. GA35 emission monitor for SF6 gas The best way to avoid SF 6 gas hazards is to continually monitor gas-insulated equipment for both quantity (to detect leaks) and quality (for current gas conditions). Then, when the gas has dropped below a certain level of purity, technicians can clean it.
