Abstract
A test method that uses a capacitive field probe to investigate the space charge distribution in low-density polyethylene (LDPE) is described. Specimens of 7-mm thickness were stressed under 100 kV DC at room temperature and for different time periods. The results indicate that the LDPE insulation layer between electrodes is occupied by positive and negative homocharges. The dependence of space charge distribution on the stressing time is also evident
