We have been studying high-field dielectric properties of polymeric insulating materials. New three-terminal electrode arrangement for more reliable dielectric measurement has been developed. Using this electrode conformation, high-field dielectric properties of low-density polyethylene (LDPE) film at power frequency were measured in wide temperature range. Moreover, we have developed a new detection method of AC dissipation current waveform. The relation between this AC dissipation current waveform and high-field dielectric properties of a LDPE film has been clarified. The purpose of this paper is to study the high-field AC conduction in electron beam (EB) irradiated crosslinked polyethylene (IR-XLPE) film at high-field and high-temperature region. The electric field dependence of tan δ and the variation of the dissipation current waveform was evaluated by using the fast rising ac ramp voltage application.
