  • SF6 circuit breaker maintenance | TD Guardian Articles

    They utilized a compressor arrangement to pressurize the arc extinguishing SF6 to a pressure of gas to enable multiple operations of this style of circuit breaker. This high pressure SF6 is released across the contacts by-way of a blast valve assembly, which is actuated during the mechanical operation of the breaker (either opening or closing).

  • SF6 Circuit Breakers - TestGuy

    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.
