The Study on Electric Power Equipment Reliability Analysis Using Statistical Method

This paper gives an overview of selected statistical methods and models commonly used in reliability engineering. The purpose of this paper is to discuss several concepts commonly applied in the analysis of equipment performance and, in particular, in predicting the remaining life of power equipment. Parametric methods are well suited for the prediction of the end of life of electric power equipment. However, care must be taken in selecting appropriate model since vastly different results can be obtained with different models fitted into the same data. Nonparametric methods are useful only when no suitable probability distribution can be fitted into the data set.
