SuperGrid Institute hosts the 11th Quarterly review of NanocompEIM 2
Since October 2016, SuperGrid Institute has been involved in the NanocompEIM 2 project. The goal of the project is to develop nanocomposites (Nanocomp) for electrical insulation materials (EIM) in order to reduce CO2 emissions and improve system reliability and availability. Financed at 50% by Innovate UK, a government organisation dedicated to research and innovation in the United Kingdom, the overall budget of the project is around 1M£ (1.1M€).

Phd Priscillia DANIEL “Electrical properties study of cross-linked polyethylene insulated cables in presence of gaseous cavities aged under DC or DC with harmonic voltages”
This study aims to examine possible impact of these harmonics in presence of microcavities. Depending on their size and on the electrical field, partial discharges (PD) can occur in these microcavities. Two types of cables have been aged: a medium voltage AC (MVAC) cable with millimetric cavities induced artificially and a model cable with an HVDC XLPE grade.
Electro-thermal simulation methodology for HVDC cable GIS termination
This paper presents a simulation methodology that can be used to evaluate the electric stresses in GIS/cable termination under different operating conditions including polarity reversal and superimposed impulses.
Follow up of space charge distributions in HVDC cable during a Pre-Qualification test using the Pulse ElectroAcoustic technique and the Thermal Step Method
In order to better understand the evolution of space charge and electric field distortions during the application of electro-thermal stresses to a HVDC cable system, the present paper shows the follow up of periodic space charge characterizations on a HVDC cable during part of a Pre-Qualification test using both the Pulse ElectroAcoustic technique and the Thermal Step Method. The focus is on the evolution of space charges distributions during load cycles and high load sequences according to the Cigré TB496 recommendation.
