초록

In order to evaluate degradation of the aged power cables, thin slices(200m) cut from the aged cables were prepared for thermally stimulated current measurements. Throughout the temperature range, 140 to $280^{\circ}C$ the TSC is greater for the aged material, and sharp peak is observed at $158^{\circ}C$ and $210^{\circ}C$.
