Abstract

In this work a study about the performance of some metal oxide surge arrester models under lightning conditions is presented. Real data were used in electrical power system simulations. Part of the local utility system was chosen to receive the lightning discharges. Discharges with 8/20 μs and 1/2 μs were applied in the evaluated system. The evaluated surge arrester models presented similar results for 8/20 μs discharges, once that they were fitted for this kind of transient. However, for 1/2 μs discharges substantial differences were obtained, mainly, between the dynamic models and the conventional model. For this kind of discharge the dynamic models have shown plausible results.
