Dynamic Loading of Transmission Lines: A Qualitative Comparison of Full-Scale Tests and Computer Simulations

This paper presents the results of the full scale testing of longitudinal loads on a 132kV wood H-frame line. The load cases are broken insulators and broken conductor/wire conditions. The longitudinal events were filmed and three cameras were used to capture the events that occurred. One camera was strategically placed at each structure adjacent to the event to capture the response to the respective longitudinal loads. One camera was placed to record the event itself. An independent study was conducted to model the same line using industry accepted software including PLS-Cadd^™ and Solid Works^™. These two programs were used in an attempt to replicate the actual results. This paper should be of interest to anyone who is responsible for the maintenance, design or relocation of comparable lines or for PLSCadd and Solid Works users modeling comparable lines.
