A space charge measurement system with high resolution at high temperature 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 with elevated temperature. 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 ℃. In this project, authors aim to develop a high resolution space charge measurement system for high temperature measurement. Furthermore, the behavior of carriers at two layer insulating materials (LDPE/EVA) is analyzed from experimental results as function of time.

开发了高温下高分辨率的空间电荷测量系统。当直流高压施加到电绝缘材料上时，空间电荷会在材料中积累。累积的空间电荷使电场扭曲。有时，电介质击穿是由变形引起的。因此，有必要测量高温下绝缘材料中的空间电荷分布。作者们一直在开发多种室温下相对低电场的空间电荷测量系统。然而，电缆绝缘材料通常在高温下使用，例如90℃。在该项目中，作者旨在开发一种用于高温测量的高分辨率空间电荷测量系统。此外，根据实验结果分析了两层绝缘材料（LDPE/EVA）中载流子的行为随时间的变化。
