A high temperature space charge measurement system with high resolution is developed. When the DC high voltage is applied to an electrical insulating material, the space charge is accumulated in the material. The accumulated space charge distorts electric field. Sometimes, a dielectric breakdown is caused by the distortion. Therefore, it is necessary to measure the space charge distribution in the insulating material. Authors have been developing some many kinds of space charge measurement systems for relatively low electric field under room temperature. However, the cable insulating material is usually used under high temperature, such as 90ﾟC.In this project, authors aim to develop a high resolution space charge measurement system for high temperature measurement. Furthermore, the behavior of carriers in insulating materials is analyzed using the simultaneous measurement results of TSC (thermally stimulated current) and time dependence of space charge.

研制了一种高分辨率的高温空间电荷测量系统。当DC高电压被施加到电绝缘材料时，空间电荷被累积在材料中。积累的空间电荷使电场畸变。有时，电介质击穿是由变形引起的。因此，有必要测量绝缘材料中的空间电荷分布。作者研制了多种室温下较低电场下空间电荷测量系统。然而，电缆绝缘材料通常在高温下使用，例如90 ℃。在本项目中，作者的目标是开发一个高分辨率的空间电荷测量系统，用于高温测量。利用热激电流和空间电荷随时间变化的同步测量结果，分析了绝缘材料中载流子的行为。
