Cause analysis of AC contactor fault noise based on correlation dimension

The correlation dimension method was introduced into the causes of the AC contactor fault noise analysis.The mutual information and Cao method decided two important parameters of the phase space reconstruction—delay time and embedded dimension.G-P algorithm separately calculated AC contactor correlation dimension with short circuit ring fracture,wear,foreign matter invasion,stronger reset spring and compared with under normal operation to judge the causes of different AC contactor fault noise.The experimental results showed that correlation dimensions are different in the different fault state.The correlation dimension of AC contactor fault noise can be used as criterion to analyses the causes of running noise.
