Abstract :
Space charge behavior at physical interfaces in cross-linked polyethylene (XLPE) films subjected to a DC field has been investigated as a function of the nature of the interfaces using the pulsed electro-acoustic technique. Aluminum, gold and carbon black-loaded polyethylene were used as electrodes to investigate space charge build-up in a single dielectric layer. A sandwich structure constituted by two dielectric films of the same nature was used to study the behavior of a charged interface.
