Compatibility Check of the Prior Information on Low Voltage Switchgear

Article Preview

Abstract:

Generally, the test data of the low voltage switchgear are very few. In order to assess the reliability more accurately, historical data are used to maximum the capacity of the test data. The premise of using the prior information is the prior data and test data should approximately come from the same overall. This is just the problem of compatibility check. In this paper, the method of fitting data and the law of testing the distribution are used to analyze both the priori and test data. Furthermore, we present a novel method of using Wilcoxon rank sum test to check the compatibility of the prior and test data of the low voltage switchgear. Both methods lead to the conclusion that the prior and the test data of the low voltage switchgear are compatible.
