  • SF6 Circuit Breaker Types, Working Principles

    2021-2-20Maintenance of SF6 circuit breaker. A common problem with 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 this, always check your breakers 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.
