Lightning induced effects on lossy multiconductor power lines with ground wires and non-linear loads - Part I: model

In the paper, which is a companion paper of part II: simulation results and experimental validation, we will present a model for the calculation of induced voltages produced by indirect lightning on multiconductor power lines. In particular, the case of power lines with ground wires terminated on non-linear loads is studied. The power line is represented by an equivalent time domain m-port, and the effects of the lightning excitation are represented through equivalent independent sources. This equivalent time-domain circuit allows treating easily non-linear terminations such as surge arresters. Streszczenie.
