Proceedings of the Institute of Electrodynamics of the National Academy of Sciences of Ukraine| Zusammenfassung: | The mathematical modeling and the analysis of distribution of electric field, currents, forces and pressures in a solid dielectric (cross-linked polyethylene insulation) are performed for appearing of different-size closely located current-conducting (in particular water) micro-inclusions. The regularities of the field amplification, increasing of the current density and the resulting electromechanical forces and pressures, caused by changes in surface charges at closely located poles of micro-inclusions, have been studied. The dependences of these values on the configuration of micro-inclusions, in particular on their mutual distances, are determined. It is shown that the resultant forces contribute to attracting of small water inclusions to large ones and create conditions for the appearance and development of water trees in solid insulation.
