Important milestone with regards to exploiting our cryostat!
They carried out a subcooling protocol that demonstrated the cryostat’s capacity to cool liquid nitrogen from 77 K to 66 K.
PhD Antoine PEREZ « Study of arc development mechanisms over solid insulators surface in CO2/fluoronitrile gas mixtures »
One of the suggested solutions is the fluoronitrile (C4F7N), a gas having alone a dielectric withstand 2.7 times higher than SF6.
[VIDEO] SuperGrid Institute demonstrated the partial discharge behaviour of SF6 substitute gases which can be used in future HVDC GIS.
We have been studying the partial discharge characteristics observed within different gases on our dedicated test platform.
[ONLINE EVENT] Offshore HVDC Grid Technology
Several members of our teams will be on live this Friday, 4th September, to participate to a Q&A session as part of the PROMOTioN project.
Measurement and behaviour of partial discharge for SF6 substitute gases in HVDC GIS/GIL
Partial discharge measurement is considered as one of the most powerful monitoring and diagnostic tools for the detection and recognition of defects for high voltage equipment.
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.
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.
DC Leakage Current Measurement Comparison between SF6 and Fluoronitrile/CO2 Gas Mixture
One of the possible SF6 alternatives that emerged in recent times is a fluoronitrile (FN), NovecTM 4710, based mixture.
[VIDEO] Find out more about the FastGrid project!
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.
Production of Graphite During the Extinguishing Arc with New SF6 Alternative Gases
Using Gibbs free energy method, a theoretical study has been conducted on SF6 replacement candidates listed above.
