Abstract
Space charge distribution was measured applying an electric field of over 1 MV/cm to 3-mm thick XLPE cable insulation. Under a high field, hetero charges were formed soon after voltage application, followed by an injection from the cathode. Then intermittent injections of charge packet from the anode took place. The space charge distribution kept changing without becoming stabilized. A simulation was done assuming hysteresis of the injection characteristics due to instability near the anode
