SF6 Breakers QUALITY for Ultra High Voltage

SF6 Breakers QUALITY for Ultra High Voltage

Sep 10, 2013At UHV level, the live tank circuit breaker requires 15 per cent of the SF6 gas as compared to the dead tank breaker of the same voltage class. That means for same leak rate, the DTB has 600 per cent more impact on the environment. The dead tank breakers are manufactured as large castings which are bound to have porosity in it.

  • Power factor testing of high-voltage SF6 circuit breakers

    At the time of production, SF6 gas circuit breakers are subject to a high-voltage withstand test. This incorporates an AC High-Potential (Hi-Pot) test transformer capable of achieving the required high-voltage levels (per industry standards). Therefore, field Hi-Pot testing is also not necessary or required. The insulating material used in the
