SF6 End-of-life joints for Power Supply

SF6 End-of-life joints for Power Supply

An intelligent circuit breaker or switching device system comprises three separate microprocessor-based units, including a condition monitoring unit (CMU) 40, a breaker control unit (BCU) 50, and a synchronous control unit (SCU) 60. The CMU 40 provides detailed diagnostic information by monitoring key quantities associated with circuit breaker or switching device reliability.
