  • SF6 Circuit Breaker Types, Working Principles Maintenance.

    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.

    The dielectric strength of SF6 increases with pressure so smaller breakers can be used at higher voltages. The breakers have a smaller footprint, so they use less real estate which can be very expensive. They are very reliable and require less maintenance than air blast or oil breakers and can operate at higher voltages effectively.
