Broken Wire Tests on a Model Transmission Line System

Abstract

This paper presents the results of broken wire tests which were conducted on a model transmission line system as part of a research project funded by the Electric Power Research Institute. The purpose of these tests was to provide static and dynamic data on the longitudinal loadings and structure responses, which are produced by broken conductors, broken shield wires, or ice shedding conditions. Results from these tests were used for comparisons with analytical methods for predicting residual static and peak dynamic longitudinal loads and for the development of a method for predicting elastic response of the structures to the dynamic loads. A design procedure is outlined for determining the dynamic loads and structure responses for prototype line systems
