A Digital Computer Program for the Calculation of Switching and Lightning Surges on Power Systems

A digital computer program for the calculation of switching and lightning surges on three-phase power systems is presented. It is designed for fast operation, statistical processing of results, and high versatility in network representation. Network elements can be symmetrical or asymmetrical, linear or nonlinear. Transmission lines can be transposed or nontransposed and may have frequency-dependent damping.
