An approach for computer modelling of dielectric relaxation, effective dielectric properties and local characteristics (electric fields and power losses) of the composites is presented. Simulations are performed for binary mixtures with regular and stochastic structures using experimentally obtained frequency dependent properties of the constituent phases as input parameters. The model is verified by comparing the computed results with the experimental data. The developed procedure is then applied to analyze interfacial charges, fields and losses in a water-treed polymeric insulation of a high voltage cable.
