Abstract

A general procedure is presented for computing the dynamic response of electric transmission line systems when one or more wires suddenly break. A computer program for performing a time history analysis for the nonlinear system has been developed. The program will compute the wire tensions, the arm loads and the ground line moments at the base of the support structures. A comparison is made between the computed results and the experimental results for a small scale laboratory model. Analysis of a full scale transmission line system shows that the impact factor as high as 4.5 can be expected due to the dynamic effects.
