The present paper aims at describing the measurement methods applied to mock-up cables in order to evaluate their dielectrics. The focus is on leakage current and temperature measurements together with the processing based upon them to assist in the selection of the more appropriate material.
The national congress of dielectric spectroscopy (SDM2) took place at LyonTech on the 6th and 7th of June at the La Doua academic campus. A number of our materials experts attended to present some of the innovative studies that are under way at SuperGrid Institute.
Accurate cable modeling is a recurrent issue for electric architecture evaluation and design, especially in specific contexts, like offshore wind farms. This paper proposes optimal analytical cable models for the technical and economic assessment of offshore wind generation systems.
This paper presents simulation and calculation results of electric field enhancement due to various cavity shapes carried out on polymeric high voltage direct current (HVDC) cables. Two aspects are considered: partial discharges (PD) in microcavities and field enhancement factor under DC.

With a new semi-automatic injection mixer and an injection molding press, the material characterization and the processing of our samples will take less time – close to industrial production thanks to the Automatic Pressure Gelation (APG) method.
This paper presents results carried out on polymeric high voltage direct current (HVDC) model cable. Two aspects are considered: partial discharge (PD) and current measurements, with the aim at investigating possible growth of voids of micrometer size.
