Metal oxide surge arresters have dynamic characteristics that are significant for over voltage
coordination studies involving fast front surges. Several models with acceptable accuracy have been proposed
to simulate this frequency-dependent behavior. In this paper, various electrical models are presented for surge
arrester performance simulation against lightning impulse. The desirable model is obtained by using simulation
results of the existing models and experimental tests. The IEEE proposed model is a proportional model can
give satisfactory results for discharge currents within a range of time to crest for 0.5 to 45 :s but due to no
existing residual voltage resulting switching current on the manufacture's datasheets decrease its performance
generally. In this study the maximum residual voltage due to current impulse is analyzed too. In additional, the
amount of discharged energy by surge arrester is focused.
Key words: Current impulse wave, dynamic characteristics, residual voltage, ZnO arresters, , ,
