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.

开发了具有高分辨率的高温空间电荷测量系统。当DC高压应用于电绝缘材料时，材料中的空间电荷会积聚。累积的空间电荷扭曲了电场。有时，饮食分解是由失真引起的。因此，有必要测量绝缘材料中的空间电荷分布。作者一直在开发许多类型的空间电荷测量系统，以在室温下用于相对较低的电场。但是，电缆绝缘材料通常在高温下使用，例如90 ﾟC。在该项目中，作者旨在开发高分辨率空间电荷测量系统以进行高温测量。此外，使用TSC的简单测量结果（热刺激电流）和空间电荷的时间依赖性分析载体在绝缘材料中的行为。
