Nanocomposites Impacts on Electrical Field Distribution Inside XLPE Power Cables

Abstract

This paper presents the electrical field stress in new cross-linked polyethylene (XLPE) nanocomposites in case of containing different partial discharges under high voltages. It has been investigated on the effect of variant nanoparticles for controlling on the electrical field distribution inside single-core power cables insulation, especially, in case of presence voids of air, water and cupper impurities with different shapes (cylinder, sphere and ellipse) inside insulation of single-core power cables. The electrical field distribution in power cable insulation and inside voids has been measured by finite element method (FEM). This research success to design different patterns of Crosslinked polyethylene insulation materials for enhancing the dielectric properties within void and inside insulator according to type and concentration of nanoparticles.
