Publikováno v: Engineering Research Express. 4:035008

In this paper, a comparative study between two open ended coaxial sensors with and without cavity is presented. Those sensors are used for materials characterization (composite, dielectric, liquid) and surface defects detection. First Galerkin’s me

Effects of electrical aging on the structural and physicochemical properties of crosslinked polyethylene (XLPE) cable insulation material

Autor: Abdallah Hedir, Ferhat Slimani, Mustapha Moudoud, Omar Lamrous, Ali Durmus, Issouf Fofana

Publikováno v: Engineering Research Express. 4:015038

The aim of this work is to highlight the evolution of physico-chemical properties of peroxide crosslinked polyethylene (XLPE) insulation material exposed to electrical aging. Specific analysis and characterization studies were carried out to determin

Impact of Thermal Constraint on the Low Density Polyethylene (LDPE) Properties

Autor: Mustapha Moudoud, Abdallah Hedir, Ferhat Bellabas, Amina Loucif, Ferhat Slimani

Publikováno v: Lecture Notes in Electrical Engineering ISBN: 9783030316792

Nowadays, Low density polyethylene (LDPE) is increasingly used as voltage cable insulating material. Owing to its excellent mechanical and electrical properties, LDPE may undergo degradation under service conditions. The focus of this work is to inve

Behaviour of Low Density Polyethylene Aged Under UV Radiation

Autor: Abdallah Hedir, Ferhat Slimani, Mustapha Moudoud, Amina Loucif

Publikováno v: Lecture Notes in Electrical Engineering ISBN: 9783030316792

Low density polyethylene (LDPE) is a usual material used within high voltage insulation systems. Like all polymers, this material may be aged after working under high voltage for a long time. The ageing process of this material is essentially caused
