Recent studies have demonstrated that fluoronitrile (FN) NovecTM 4710 and fluoroketone (FK) NovecTM 5110 show higher dielectric strength than SF6. These gases can be mixed with a buffer gas such as CO2 and technical air to have suitable dielectric properties for high voltage insulation applications.
SuperGrid Institute is aiming to test the new superconductive tapes that will be used in future current limiters, as one of the partners involved in the FASTGRID project.
This morning, SuperGrid Institute presented at the second conference on Power Transmission in Africa (Johannesburg) its vision on new transmission technologies and architecture, shaping the future grids. With emphasis on the fantastic opportunity that the latest HVDC technologies and solutions represent for a robust and interconnected power system in Africa, able to address major issues linked to energy transition.
In the framework of the research activities of the High Voltage Substation Equipment program of SuperGrid, it has been proposed to introduce such species by means of an evaporative liquid spray. The interaction between injected droplets and the mixture of hot gases successively flowing into the chamber and vented outside the chamber during the mechanical separation of the electric contacts should allow spray evaporation and transport of the modified gas mixture towards the arc region.
This Tuesday the 4th of February, at the European Commission’s Directorate General for Energy, Bruno Luscan, CTO of SuperGrid Institute, presented the company’s vision on the importance of the role of HVDC links within AC/DC networks.

The work of this thesis focuses on the experimental development of a passive and biphasic cooling system to cool down power electronics. Some of those modules are mean voltage power converters developed by Supergrid Institute. Some constraints have been imposed upstream to this project. While some limitations are of the technological nature, other constraints are related mainly to the environmental and biological aspects. The first part of this thesis was to find a suitable cooling system that could be adapted to the project specifications. After some research, we decided to build a loop thermosiphon filled with NOVEC 649.
SuperGrid Institute has achieved a major milestone in the development of 10 kV Silicon Carbide (SiC) devices such as 5A BJT and 50A PIN diode as part of its work on developing innovative solutions for MV converters. Recent tests revealed outstanding switching performances.
SuperGrid Institute wishes you an electric new year! [...]
This Tuesday, the 17th of December, SuperGrid Institute organised a Climate Collage event for its team. The Climate Collage is an interactive workshop based on collective intelligence that raises awareness of climate change and allows participants to gain a better understanding of the the complexity of this issue in a fun and easy way.
