The influence of the semicon-insulation interface on the thermally stimulated current spectra of XLPE cable samples

The thermally stimulated current (TSC) technique is a powerful way of investigating the characteristics of injected space charge induced by high voltage poling. In this paper, TSC measurements on XLPE high-voltage cable insulation are reported which show that differences in the electrode-polymer interface conditions are responsible for differences in space charge injected under high fields.
