Abstract :
Recently, the pulsed electro acoustic method - PEA - has been adapted to perform space charge measurements in organic dielectrics under electron beam irradiation and during relaxation, considering short-circuit and open-circuit conditions for the insulation. On the other hand, a model has been developed in order to understand the behavior of space charge in spatial conditions. The aim of this paper is to present the numerical model, and to compare simulated results with experimental ones, obtained with the short-circuit PEA and the open PEA, for a polytetrafluoroethylene (PTFE).
