Abstract:
Transient over voltages that happen in the power system are the major factor of equipment harm in the electrical system. One of defensive device which can diminish the lightning impact, protect high and medium voltages of system device under switching overvoltage or lighting is metal oxide surge arrester (MOSA). Frequency-dependent characteristic of arrester have been simulated by IEEE, Pinceti and Fernandez & Diaz models. The models parameters were calculated by using trial and error method in the ATP/EMTP software. Results suggest that the Pinceti model gives better residual voltage responses compared to other models. In addition, the Fernandez & Diaz model is the best surge arrester model particularly with respect to the quenching time.
