Abstract. In this paper, an analytical model based on the percolation theory and a numerical model based on Monte Carlo method was developed and used to study the electrical conductivity behavior of an organic insulator under high electric field. The percolation model considers that the real network of organic insulator is consisted of the traps randomly distributed and connected to each other by conductance Gij. The phenomenon of charges trapping and detrapping depends strongly on certain parameters such as the intensity of the applied electrical field, the dead ends length of traps, and the random distribution of the energies of traps constituting the dead end. Using gaussian energy distribution negative electrical conductivity law as exponential function of the electric field was found. The simulation results were compared with an analytical model, they are in agreement, proving the accuracy of this model.
