Abstract: 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. On-line analysis performed by the CMU provides information facilitating the performance of maintenance as needed and the identification of impending failures. The BCU (50) is a programmable system having self-diagnostic and remote communications. The BCU replaces the conventional electromechanical control circuits typically employed to control a circuit breaker or switching device. The SCU (60) provides synchronous switching control for both closing and opening the circuit interrupters. The control processes carried out by the SCU reduce system switching transients and interrupter wear. The intelligent circuit breaker or switching device system improves system operation and equipment maintenance.
