Modeling equivalent circuit cable insulation 6 (10) kV for the evaluation of partial discharges taking into account mode of operation in the distribution network

In the article the results of experimental studies to assess changes in the parameters of partial discharges at the existing cable lines 6 (10) kV with impregnated paper insulation. Examples of variations of the parameters partial discharges distribution diagrams of partial discharges in phase and amplitude taking into account climatic conditions and modes of operation of the cable line with impregnated paper insulation. The questions of mathematical modeling equivalent circuits of the dielectric parameters of the evaluation of partial discharges in the insulation of cable lines 6 (10) kV in view modes in a city electric networks. Developed a virtual simulation model, based on the equivalent circuit isolation, to assess changes in the parameters of partial discharges under the influence of defects in the dielectric on each other with the previously established experimental data.
