Algorithm of Change Points Detection for a Trip Coil

Abstract:

A predictive maintenance approach of vacuum circuit breaker is based on the circuit breaker coil current signal. The method identifies the critical time instants in the close coil current, to be used for diagnostic analysis. Change points detection based automatic signal segmentation plays a significant role in recognition-oriented signal processing. In this paper, we addressed the algorithm of change points detection for applications in fault detection for a trip coil. The algorithm includes three parts which are data smoothing, extrema search and K-Means clustering. The experimental results show that this algorithm is effective.
