Abstract :
The electrical ageing behaviour of a dielectric material in an adverse environment may be investigated by a study of its polarization and dielectric behaviour. The present work reports such a study with polyethylene under AC stress in a humid environment. In addition, the polarization and dielectric relaxation behaviour have also been correlated with studies of thermally stimulated discharge currents (TSDC) and thermal transient currents (TTC)
