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.

W artykule zaprezentowano model obliczeń napięć indukowanych podczas nie bezpośredniego wyładowania na wieloprzewodową linię zasilania. Uwzględniono przewód uziemiony podłączony do nieliniowego obciążenia.

Using the procedure and the model analysed in the companion paper part I: model, in this paper simulations are carried out in order to evaluate the overvoltages produced on a multiconductor line. In particular, the shielding effect produced by ground wires and the role of surge arresters are investigated. The model has also been validated using experimental results.
