Abstract :
We have investigated the thermally stimulated current (TSC) in low-density polyethylene (LDPE) film and surface potentials built in the LDPE films due to excess charges injected from a needle electrode, using 10, 15 and 20 needle-plane electrode systems. The amount of charge injected and its depth were determined from TSC and thermally stimulated surface potential (TSSP) measurements
