The phenomenological approach to dynamics of the intrinsic electric conductivity of dielectrics in the electric field was used for analyzing the respective contribution to dielectric losses. The proposed differential equation contains only two parameters - the effective time TF of conductivity decay in electric field, and time TR describing the rate of conductivity recovery after switching field off. The proposed approach predicts the linear dependence of specific conductivity of dielectrics on the sample thickness experimentally confirmed by Du Pont [1] for Teflon FEP. The field, time and frequency dependences of intrinsic conductivity G(t,ω,E) and related dependences of dielectric losses component ε(ω,E) was calculated, analyzed and illustrated by published experimental data.
