Herein, we report a novel technique to develop remote assessment and observation for partial discharge events under high voltage cable systems output. Finite element modeling of the cavities bided in the insulators which are the source of Partial Discharge signals occurred in a 3-d section of a typical 230 KV high voltage XLPE 3-phase cable. All electromagnetic related equations are solved using FEM software. The idea is to consider the permittivity constant in cavities as a nonlinear function during the solving process. This function is related to electric field value inside each cavity. This modeling leads to a new approach in simple modeling of PD phenomena in the H. V. apparatus with the big amount of destructive PD cavities. In continue, the obtained waveform is illustrated respecting to the main power line waveform.
