Priority estimation for overhead-to-cable reconstructions regarding reliability indices

The article presents a method for estimating the priority of new investments in distribution networks from a technical standpoint. The analysis focuses on overhead line-to-cable reconstructions which are due to the expected enhanced performance and quality very attractive for distribution companies. A comprehensive example based on an actual utility system is described in this article, and predictive reliability estimated. According to the analysis of reliability indices variation, recommendations of reconstruction locations, where the reliability objectives can be achieved, are made.
