要約(英語): The leakage current behaviors of MOVs (Metal Oxide Varistors) having different conditions of manufacturing process were investigated and distinguished into 4 categories. It is confirmed that the behavior of leakage current during DC application are quite similar to those during AC application. The initial leakage current, dominated by the applied voltage ratio, and the temperature during the ageing test are the principal factors on variation of leakage current. As the index to judge the degradation, the varistor voltage at DC several μA to mA in both directions is more sensitive and effective than the behavior of leakage current.
