| Abstract: | The pulse-degradation mechanism of ZnO varistors under impulse currents is suggested in this paper using thermo-stimulated current spectrum as an analysis me- thod. Under the action of pulse currents, many parameters of ZnO ceramic mate- rials, such as:the schottky barrier height of intergranular phase: thereby thermionic emission; leakage current and the weak bound ions etc., were discussed. Based on a lot of experiment, ZnO ceramic materials exist thermoreleasing cur- rent phenomena were found and discussed. |
