Abstract：The space charge distribution of filler free epoxy resin at temperature below 313K and above 343K are measured with the pulsed electro-acoustic (PEA) method. The space charge distributions under different electrical field at each temperature are also investigated. The results show that the space charge characteristics at each temperature had obvious diversity. The influence of the water content on the space charge generation is also shown and discussed.
