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 ...

Investigation of diagnostic techniques for metal oxide surge arresters [PDF]
IEEE Transactions on Dielectrics and Electrical Insulation, 2005 Gapless metal oxide surge arresters (MOSA) have been available in the market for many years since they were first introduced in the 1970's. The aim of this study is to investigate some reliable diagnostic techniques to assess the condition of a metal oxide surge arrester when subjected to severe lightning strikes in the field.
