Accurate Judgment

In order to monitor the operating status of the circuit breaker, designed a multi-signal processing system based on the labview. The system acquisite multiple signals synchronous, and combined with MATLAB. Signal feature is extracted with time domain eigenvalues, EEMD decomposition, wavelet decomposition, and finally sent into ELM. The results demonstrate: that the system can achieve the accurate judgment of the operation state of the circuit breaker.
