The effects of electrical degradation on the microstructure of metal oxide varistor [PDF]

2001 IEEE/PES Transmission and Distribution Conference and Exposition. Developing New Perspectives (Cat. No.01CH37294), 2002
In this paper, the findings from systematic experiments with the purpose to determine the degradation effect of single and multiple current pulses on the microstructure of the Metal Oxide (MO) varistor are described. Six distribution class varistors from one manufacturer were used in these experiments.

Current limiting and negative differential resistance in indium oxide based ceramics [PDF]

, 2009
Indium oxide based ceramics with bismuth oxide addition were sintered in air in the temperature range 800-1300 ºC. Current-voltage characteristics of In2O3-Bi2O3 ceramics sintered at different temperatures are weakly nonlinear.

Assessment of MOV Deterioration under Energized Conditions

Energies, 2020
Metal oxide varistors (MOVs) are widely used to protect electrical and electronic devices that are very vulnerable to surges due to the low insulation level of the equipment. MOVs deteriorate gradually due to manufacturing defects, mechanical and thermal

On the Computation of the Voltage Distribution along the Non-Linear Resistor of Gapless Metal Oxide Surge Arresters

Energies, 2018
The voltage distribution along the non-linear resistance of metal oxide surges is of great importance for their proper operation, since the non-uniform potential distribution results in higher thermal stresses of the varistor discs near the high voltage ...
