A Study of Kurtosis-Based Dictionary-Diagnosis Method against Switch-Current Circuit Faults

Abstract:

For the purpose of solving the problem of diagnosing the Switched current circuits’ fault,a location algorithm based on information kurtosis was proposed.Data acquisition board or ASI-Z software was used to gather the data of the fault circuit output terminal.Then information Kurtosis of the Switched current circuit time domain response was calculated.Finally fault dictionary was built to classify faults.The location algorithm was simulated in a practical circuit.The results show that the location algorithm is use to simplify the structure of fault dictionary,and classify the faults,and it is applicable to diagnosising switch current circuit fault.
