传导电流可测的PEA空间电荷测试系统
PEA Space Charge Test System with Measurable Conduction Current
摘要
Abstract
Conduction current will reflect many microscopic characteristics of carrier transport process in dielectric. To investigate the relationship between the space charge distribution characteristics and conduction current,a set of sim-ultaneous measurement system based on Pulsed Electro-Acoustic( PEA)method has been designed in this paper. This test system designed an electrode system,by dividing the lower electrode into several parts,so as to realize the function of simultaneous measuring conduction current and space charge. Tests of space charge distribution and con-duction current are carried out on PE and ZnO materials,respectively. The results show that the developed system can measure the space charge and conduction current in the dielectric material at the same time and the test results agree well with the conclusion in the relevant reference.关键词
