  • Hints for maintaining type SP SF6 power circuit breakers

    SF6 circuit breaker maintenance: what should utilities be doing? This has resulted in hardened o-rings which leak in some valves. A contributing factor is the heater which is located below the air valve. The first thing to check is to make sure that the circuit breaker lever system is set correctly. This is accomplished by using
