Online Monitoring of High Voltage Circuit Breaker By Multi-resolution analysis of Mechanical Component Signals

In this paper, a new solution for automated analysis of circuit breaker operation based on a record of waveforms taken from a circuit breaker test unit is presented.The Solution is implemented based on status and analog signals acquired form controlling relays and mechanical moving systems. Multi-resolution analysis is utilized to extractedwaveform features and an expert system is used for circuit break fault detection. The experimental results show therobustness of the extracted features and their ability to detect faults in circuit breakers
