SuperGrid Institute’s experts are ready for Jicable HVDC’21!
We are thrilled to participate in Jicable HVDC'21 with no less than 5 appearances in the programme.
SuperGrid Institute is taking part in the WindEurope Electric City 2021 conference
We will be flying the French colours high on our stand in the Business France Pavilion at this onshore and offshore wind energy event.
Ocean DEMO awards: SuperGrid Institute is selected for EU funded project
Thanks to the Ocean DEMO’s support packages, we will be able to test our innovative offshore technology in real marine environments.
Epoxy composite with hBN fillers compatible with industrial application in electrical equipment
A synergetic effect between hBN and alumina has been observed regarding thermal and electrical properties. A 500% increase in the thermal conductivity could be achieved with a limited impact on viscosity increase.
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€).

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.
SuperGrid Institute’s has a significant presence at Jicable19
This year, for the first time our presence at PCIM Europe 2019, was noticeable with our stand from 6th to 9th May. At the conference, and as power electronics is at the heart of our innovations, SuperGrid Institute was invited to present during the « Smart Transformers » special session.
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.
Development and Set-up of a Non-intrusive Technique for measuring Space Charges in Specimens of dc cables
This paper presents a procedure for designing a power converter to produce power pulses in the conductive parts of a cable (core or shield) for non-invasive space charge measurements with a thermal wave.
