Nano-enabled metal oxide varistors
IEEE Transactions on Dielectrics and Electrical Insulation, 2009Zinc oxide based metal oxide varistors (MOV) are widely used electrical surge protection components. The design of modern high power, high-density electronic systems necessitate the need for smaller footprint, higher current density and higher nonlinearity MOVs.

Pressure effects on metal oxide varistors
Applied Physics Letters, 1976Preliminary results on the strong dependence of current-voltage characteristics of ZnO-based metal oxide varistors on pressure up to ∼5 kbar (nominal) are reported. This letter perhaps constitutes the first pressure study on electronic ceramics.

Surge ageing of metal oxide varistors
2015 IEEE Electrical Insulation Conference (EIC), 2015The objective of this paper is to analyze the ageing of metal oxide varistors (MOV) due to surges by the changes of the nonlinear behavior. The surge arrester installed in the field is submitted to the lightning stress superposed to the power frequency voltage, and so, submitted to an ageing process due to both cumulative stresses.

Electrothermal and Overload Performance of Metal-Oxide Varistors
IEEE Transactions on Power Delivery, 2020The energy absorption capability of metal-oxide varistors, decidedly influenced by the electrothermal processes occurring within their microstructures, is a vital parameter for the effective surge protection. This paper proposes a numerical model for the simulation of the electrothermal phenomena occurring in metal-oxide varistors.

Impact of Metal Oxide Varistor on the Occurrence of Ferroresonance Oscillations in Transformers
2025 International Conference on Electronics and Computing, Communication Networking Automation Technologies (ICEC2NT)The impact of a parallel Metal Oxide Varistor (MOV) on the transformer's ferroresonance oscillations is examined in this paper. It is anticipated that an arrester generally causes ferroresonance mitigation.
