A computer model of the secondary arc in single phase operation of transmission lines

A computer model of the secondary arc is described which has been developed for use in system simulation studies. The computer model is based on the mathematical model described by A.T. Johns et al., which is largely empirical and was obtained by fitting mathematical equations to experimental data. The computer model utilizes the Electromagnetic Transients Program (EMTP). Block diagrams of the computer model as well as a listing are provided. Simulation results utilizing the computer model compare favorably with results of a previous simulation and field test results.<
