Longitudinal Loads From Broken Conductors and Broken Insulators and Their Effect on Transmission Lines

A review of a study of the longitudinal loads on a suspension tower and the dynamic response of aans- transmission line following a broken conductor or dropped insulator is presented. Included are the results of full-scale tests conducted on an existing electric transmission line. A new technique for calculating the maximum impact load based upon the conservation of energy is explained. Predicted values of the peak force using this technique are compared to the recorded test values and published data.
