Research Abstract |
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.
