  • Abstract
    This paper presents iterative EMT algorithms for Surge Arrester, also commonly named Metal Oxide Varistors, within 2 different simulation solvers; the State-Space-Nodal solver of ARTEMiS and the nodal admittance method of HYPERSIM. The proposed algorithm, based on fixed-point iteration, allows precise simulation of nonlinear models with minimal extra simulation time cost. Cases are presented in the paper in which the iteration feature clearly improves the simulation accuracy.
