Abstract
In this study, electrical properties of polyethylene of raised temperature resistance (PE-RT) have been studied through an examination of AC conductivity, dielectric constant, and space charge distributions. A dielectric constant was investigated by Dielectric Analyzer (DEA). Measurements of space charge distributions for PE-RT were carried out using Pulsed Electroacoustic (PEA) techniques, and it was possible to observe the negative charge near the cathode overlapped with the positive induced charge peak, the polarity of which remains unchanged after a short circuit.
