عنوان المقالة:Study of Physical Parameters Change, by Static Regime Modeling, in a Heterogeneous Insulating Material XLPE, Containing Three Cavities, of a Medium Voltage Cable
The Partial discharges (PD) in micro cavities within the insulation of HV power cables drastically affect their performances, and their reliability. In the present work, we suggest a study on the influence of defects (cavities) and their positions by the static regime modeling, on the potential distribution and the physical constraints namely the electric field, the temperature and the electromechanical pressure, in a heterogeneous insulating material (containing three cavities) of a single core cable for medium voltage. This study joins in the general framework in reliability of the synthetic insulation and aims at applying the finite difference method. The results obtained, were successfully compared to those published in the literature, are considered very satisfactory.
