Abstract :
Our work was to study the influence of temperature from 20°C to 80°C on space charge formation on low-density polyethylene, with and without antioxidant. The pulsed electro-acoustic (PEA) method and DC conduction measurements were used to follow the space charge formation under high electric field (55 MV/m) and charge de-trapping as a function of the temperature.
