Abstract

The pulsed electro-acoustic method was used as a nondestructive measurement technique of space charge distribution in dielectric materials. In our work presented here, we measured simultaneously the space charge distribution and conduction current in the low-density polyethylene samples with elevated temperatures up to 80°C and electric field up to 40 kV/mm. The temperature and electric field dependences on the space charge distribution and conduction current were analyzed, and the characteristics were discussed
