The objective of this paper is to introduce analytical models for accurate prediction of failure probabilities of existing shield wires and to recommend a time window for wire replacement at an acceptable failure threshold. Ductile and strength tests results and failures records of shield wires were examined to determine the trend of wires deteriorations as they age. Since most of failures occurred...
This paper introduces a new model and the associated computer program for the prioritization existing overhead transmission lines for maintenance or refurbishment. The model calculates the priority risk index (PRI), which is the product of failure probability, line condition function, and failure consequences function. The failure probability of a line is calculated using the maximum capacities of...
