This paper aims at the detection and characterization of partial discharges (PD) in GIS under HVDC constraints in the presence of a protrusion/metallic particle on the high voltage conductor.
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.
