Get PriceJun 05, 2020A common problem of an SF6 circuit breaker is gas leakage. When leakage occurs, the gas pressure decreases. This reduces the quenching ability of the circuit breaker. To avoid that, always check your breaker often. You can check that via the pointer of the gas gauge. If the gauge shows a decrease in gas pressure, subject it to a gas leakage test.SF6 Gas Leak Detectors in Saudi Arabia | CEPCO Sales
