Mathematical model for the evaluation of dielectric properties of inner layers of insulation in three-core belted cables

Abstract

This paper presents a discussion of properties of the modified inspection scheme, which is used in practice of evaluation of partial capacitances and dielectric dissipation factor of insulating layers in three-core power cables by using aggregate measurements. The applying of the proposed modification allowed to develop an alternative approach for the evaluation of partial capacitances and dielectric dissipation factor.
