Abstract :
The present paper reports the results of a study of electrical ageing of low density polyethylene (LDPE) aged in humid environment (0.1 M NaCl) at an AC stress of 6 kV/mm, 1 kHz, at room temperature (RT) and at 65°C for up to 454 hours. For this study the dielectric spectroscopy in the frequency range of 10-5 Hz to 106 Hz has been employed to provide electrical analog models of the ageing
