A computer program to study the dynamic behavior of an electric transmission line system when wires suddenly break has been developed by the authors. All three of the line elements: the support structures; the insulators; and the wires are included in the analysis. A lumped mass model is used in the nonlinear time history analysis. The input consists of the physical parameters of the line system and the location of the broken wires. The output consists of the wire tensions, support structure arm loads, and support structure ground line moments. The program will be of use to engineers involved in the design of electric transmission line systems.
