PEA Space Charge Test System for Conduction Current Measuring
Testing the Conduction current can reflect many microscopic characteristics of carrier transport process in dielectric. To investigate the relationship of space charge distribution characteristics and conduction current in the dielectric material, a set of simultaneous measurement system based on Pulsed Electro-Acoustic (PEA) method was designed. This test system focusing on designing the electrode system, by deviding the lower electrode for several parts, the function of simultaneous measuring conduction current and space charge was realized.Tests of space charge distribution and conduction current were 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.
