Absorption and Polarization Phenomena in Cross-Linked Polyethylene Films

Margarita E. Borisova, Julia K. Osina

Abstract


The charging and discharging currents of the cable polyethylene insulation before and after thermal aging were experimentally studied and analyzed. Analysis was carried out on the basis of equivalent Maxwell and Voigt circuits. Thermally stimulated depolarization current in open and shorted circuit and the kinetics of charge accumulation were studied. The nature of the charge accumulated in film by applying a constant electric field and the charge storage mechanism were determined. 


Keywords:
