Abstract
In light of the sure protection function, the most important factors of a varistor are the clamping voltage ratio and degradation characteristics. The degradation characteristics of Pr/Co/Cr/Er co-doped zinc oxide varistors were investigated by impulse currents (0.4~2.1 kA) stress for the specified content of (0.5 and 2.0 mol%). The varistor doped with 2.0 mol% exhibited the best clamp characteristics, with the clamp voltage ratio (K) in the range of K
