“…odern power grids are intrinsically susceptible to overvoltages as they employ equipment of low insulation levels [1]. The root cause of more than 40% of unexpected failures of electronic equipment is lightning, based on the United States National Fire Protection Association [2]. Thus, extensive research is conducted focusing on the field performance of surge protective devices (SPDs) [3]- [8] since the surge protection of low-voltage power grids is of paramount importance for their reliability.…”

This work introduces an experimental methodology for time-domain modeling of low-voltage surge protective devices (SPDs), accounting for their sparkover performance as well as their resistive, inductive, and capacitive behavior. The modeling procedure is demonstrated through an application to a combination type SPD connected to the DC side of electric vehicle charging stations. An equivalent circuit model is developed based on experimental records acquired from applied voltages and currents of a wide frequency range and energy content. The developed lumped-circuit model yields results in very good agreement with experimental data regarding sparkover voltage, residual voltage, and energy absorption of SPDs, as illustrated through ATP-EMTP simulations. The proposed methodology can be an effective tool for surge protection and insulation coordination studies.
