    1997-7-26SF6 gas is an inert gas with dielectric strength and arc-extinguishing qualities. In SF6 breakers, the rate of rise of dielectric strength is very high and the time constant is very small. This provides another type of oil-less circuit breaker. However, the life of the contacts is short when compared to that of the vacuum

  • Switchgear:High-voltage (transmission) switchgear

    High-voltage (transmission) switchgear System considerations The transmission of high powers over long distances necessitates the use of High (HV), Extra High (EHV) or Ultra High (UHV) voltages. Historically, these voltages were classed as 72.5kV and above. The lower voltages were introduced first, and as the technologies have

It does not cover direct current (dc) switchgear, low-voltage switchgear (voltages up to 1000 volts ac) and switchgear used on single-phase ac traction systems. Although switchgear is generally reliable and performs well, failures, though rare, may be catastrophic.
