SF6-Air leakage and quality for powergrid

SF6-Air leakage and quality for powergrid

The best way to avoid sf6-gas 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. Here are just a few of WIKA USA's innovative sf6 gas solutions for greater
