Description
Summary:Transient currents in low-density polyethylene have been investigated at various temperatures, field strengths and for nonconditioned and conditioned samples, under vacuum and ambient air conditions. Anomalous charging and discharging currents have been observed. The anomalous discharging current is almost the mirror image of the anomalous charging current. Two patterns have been observed for temperatures below and above 50°C. Three characteristic zones have been identified, from which one may obtain information about dielectric polarization, bulk conduction effects and electrode effects and diffusion.
