Degradation Mechanism of ZnO Ceramic Varistors with the Time on the DC Stress Test
DC 스트레스 시간에 따른 ZnO 세라믹 바리스터의 열화기구
Abstract
The objective of this paper is to demonstrate degradation phenomena through DC degradation tests and predicts degradation phenomena as a function of time from the tests. The ZnO varistor used in this investigation were fabricated by standard ceramic techniques. Especial, these were sintered in nitrogen atmosphere, at 2 h, for
