Comparison of different metal oxide surge arrester models
Abstract
Two methods for modeling metal oxide surge arresters are presented and compared: the surge arrester model proposed by IEEE Working Group 3.4.11 and the simplified surge arrester model proposed by Pinceti and Giannettoni. The comparison of model performances and accuracy is conducted in the program package EMTP–RV. Detailed instructions describing the implementation of both models into EMTP–RV environment are also provided. It is demonstrated that the simplified model proposed by Pinceti and Giannettoni yields highly satisfactory results especially taking into consideration a much easier implementation of that model in the EMTP–RV environment in relation to the IEEE model.
