Residual Voltage Tests of 4.5 kV Metal Oxide Surge Arrester
2023 14th International Conference on Electrical and Electronics Engineering (ELECO), 2023 Overvoltages can cause various malfunctions in electrical power systems and high voltage facilities. Metal oxide surge arresters (MOSAs) are used to prevent overvoltage-related malfunctions in electrical power systems and high voltage facilities. MOSAs protect the system from high amplitude currents by conducting overvoltage-induced discharge currents ...

Analysis and comparison of metal-oxide surge arrester models
Technology audit and production reserves, 2017 The objects of the research are: full and simplified dynamic models of surge arresters, as well as the model of surge arrester in the form of a nonlinear resistor. For the simulation of the voltage-current characteristics, in the latter case the approximation was used, describing by one expression both switching and lightning surge domain.
