Sažetak

In this article, electrical and magnetic field analysis in XLPE insulated power cables is performed. The defects that may occur in the insulation material have been tried to be realized considering different conditions. A lot of variations have been obtained by changing the location of the defect in the insulation material, the shape of the defect, the size of the defect and the type of the defect. The effect of all the factors that make up the defect on the distribution of the electric field and magnetic field is shown and the causes of malfunction in the cable are examined. The electric field analysis for 1 × 240/25 mm2 was performed by using different forms with equal areas. The magnetic field analysis was performed for balanced and unbalanced load cases to 3 × (1 × 240/25) mm2 and 3 × 240/25 mm2 cable with XLPE insulation.
