220kv Installation Maintenance Instructions SF6 Power Circuit Breaker SF6 carts

Feb 20, 2021 · Maintenance 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.
