Power tests successfully performed by SuperGrid Institute for the FastGrid Project
We are currently analysing the experimental data issue from these power tests in order to write our report for the project.

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.
One of the possible SF6 alternatives that emerged in recent times is a fluoronitrile (FN), NovecTM 4710, based mixture.
With the FastGrid project completion date just a few months away, find out more about the ins and outs of the project in this video filmed at our premises.
Using Gibbs free energy method, a theoretical study has been conducted on SF6 replacement candidates listed above.
SuperGrid Institute will be able to develop an effective partial discharge monitoring system for the future SF6 free high voltage equipment.
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.
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.
