Abstract

Aging may increase the number of failures that underground power distribution cables undergo. Recent works have investigated this problem and proposed repairable failure models that consider the effects of aging as well as of loading conditions. This paper examines and assesses the performances of two models; one of them is called IEC-Arrhenius-Weibull, because it combines the failure rate function of the Weibull distribution with the Arrhenius relationship and the standard IEC 60287-1-1. First, we analyze the modeling assumptions, the methods for incorporating loading conditions, and the approaches for calculating the model parameters. And second, we evaluate the performance of the two models through computer simulations, sensitivity analysis, and cable rankings. The results strongly suggest that the use of the Arrhenius relationship to calculate the scale parameter of the IEC-Arrhenius-Weibull model leads to provide reduced failure rates that may affect cable maintenance, and that this model significantly depends on its shape parameter to describe different degrees of aging. Thus, this paper helps stakeholders to identify a realistic model for underground cable management.
