Abstract

The present paper reports the results of a study of electrical ageing of low density polyethylene (LDPE) aged in a humid environment (0.1 M NaCl) at an AC stress of 6 kV/mm, 1 kHz, at room temperature (RT) and at 65°C, and cross-linked polyethylene (XLPE) AC aged in humid environment (water) at an AC stress of 6 kV/mm, 50 Hz, at RT, for an extended period of time. For this study, the dielectric spectroscopy data in the frequency range of 10^-5 Hz to 10⁶ Hz and their comparative analysis, have been used to provide electrical analog models of the ageing
