Parameter Determination forModeling Systems Transients—Part V: Surge Arresters

The performance of surge arresters during electromagnetic transients on power systems can be simulated with Electromagnetic Transient Program (EMTP)-type computer programs. This paper discusses the steps to be performed for deriving the parameters needed to represent gapless metal-oxide surge arresters in transient simulations. The paper includes a summary of the mathematical representation, guidelines for choosing appropriate parameters, and the conversion procedures used to obtain parameters.
