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.

Measuring the energy handling capability of metal oxide varistors [PDF]
16th International Conference and Exhibition on Electricity Distribution (CIRED 2001), 2001 Metal oxide varistors are widely used in many power electronics circuits to protect against transient overvoltages. Certain applications are very demanding on the energy handling capability of the varistors. This paper gives an overview of the failure modes of ZnO varistors and investigates their characteristics when subjected to repetitive current ...
