Abstract

This paper considers the behavior of accelerated ageing on polyethylene materials containing cavities involving its
dielectric performance in terms of the electrical, chemical and morphological properties. As a result of internal discharges in an air-filled cavity within polymeric materials, this ageing mechanism might gradually deteriorate and progress further to complete failure. In this experiment, low density polyethylene (LDPE) test samples are made using a multiple layer technique. The results detail the effect of electrical ageing corresponding with analysis of partial discharge measurements. In addition, the combination of electrical properties and chemical compositions is examined experimentally to diagnose the electrochemical consequence of ageing using infrared spectroscopy and dielectric spectroscopy techniques.
