Abstract:

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.
