  • Low SF6 action - Electric power transmission distribution

    I can say that all the dead-tank SF6 breakers I've worked with (mitsubishi, siemens, abb) at the 115kV or higher level all trip themselves out on low-low gas. Avoiding this would require modifying the manufacturers wiring from what I've seen. Itkind like messing with an old oil breaker anti-pump or anti-slam scheme. You just wouldn't do it.

    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.
