Abstract
This paper presents an approach to evaluate the reliability of distribution network components (transformers and underground cables) by modifying the components failure rate based on its operating conditions. Expressions to determine failure rates of each component are established as functions of equipment loading, cable joints and cable length. It is shown that reliability curves of transformers and underground cables based on exponential and Weibull distributions derived using modified failure rate gives more realistic results.
