Metal Oxide Varistor (MOV) Lifetime Estimation with Impulse-Based Testing in PV Inverter Systems

2022 IEEE 13th International Symposium on Power Electronics for Distributed Generation Systems (PEDG), 2022
Surges caused by lightning strikes could damage electrical components in photovoltaic (PV) systems. Metal oxide varistors (MOVs) are commonly used to protect PV systems from lightning strikes.

Methodology for Metal Oxide Varistor design applied to Fixed series capacitor

2022 IEEE Engineering International Research Conference (EIRCON), 2022
A series capacitor bank includes internal and external events with high energy through the circuit in a transient time; therefore, a series capacitor bank is equipped with a sophisticated Metal Oxide Varistor (MOV) bypass protection system.

Simplified Thermal Computation of a Metal Oxide Varistor Element under a Lightning Impulse Current Injection

IEEJ TRANSACTIONS ON ELECTRICAL AND ELECTRONIC ENGINEERING, 2021
A simple thermal computation procedure of a metal oxide varistor (MOV) element, in which an impulse current is injected, is presented. The heat in the MOV, composed of many small cells, is computed with the discretized heat transport equation.

Power dissipation of XnO-based metal oxide varistors (MOVs) for electronic circuit protection

Proceedings. 7th International Conference on Solid-State and Integrated Circuits Technology, 2004., 2005
Power dissipation in the high-current (upturn) region of the current-voltage characteristic of ZnO-based metal oxide varistors (MOVs) has been observed to be influenced by the ZnO grain resistivity and nonlinearity. Power dissipation lower than 20 kW was observed in samples with lower grain resistivity values (less than 1 /spl Omega/cm) and higher ...
