Computation of energy absorption and residual voltage in a fourth rail LRT station arresters in EMTP-RV: a comparative study

This paper presents a study on the performance of a fourth rail direct current (DC) urban transit affected by an indirect lightning strike. The indirect lightning strike was replicated and represented by a lightning-induced overvoltage by means of the Rusck model, with the sum of two Heidler functio...
