Prediction of power cable failure rate based on failure history and operational conditions

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

In this paper, the failure causes of cables are classified into two types, random and ageing. The piece wise power law non-homogeneous Poisson process and stochastic electro-thermal model is proposed to predict the total annual and ageing failures, respectively, and the amalgamation of the two models is used to estimate the random failures. The proposed methodology is successfully applied to real data of vintage unjacketed XLPE cables. The result shows that these cables have average 39 years of ageing life. However, failure of these cables is dominated by random failure which cause many of these cables to fail earlier in their life.
