Understanding of PD phenomena is mandatory to evaluate the performance of PD measurement systems in function of gas composition.
They carried out a subcooling protocol that demonstrated the cryostat’s capacity to cool liquid nitrogen from 77 K to 66 K.
One of the suggested solutions is the fluoronitrile (C4F7N), a gas having alone a dielectric withstand 2.7 times higher than SF6.
We have been studying the partial discharge characteristics observed within different gases on our dedicated test platform.
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.
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.
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.
