A validated high-voltage arrester model for transient network analyzer applications

This paper describes the development of a dynamic surge arrester model for use on a transient network analyzer to evaluate the arrester instantaneous voltage, current and total energy during conduction. Based on the results of duty-cycle tests, a model is proposed for which three sets of parameters were found to match three different makes of 72 kV arrester. The relative values of these parameters are discussed as well as a general set of parameters that could represent all three types of arrester.
