With a new semi-automatic injection mixer and an injection molding press, the material characterization and the processing of our samples will take less time – close to industrial production thanks to the Automatic Pressure Gelation (APG) method.
Two high voltage properties – DC conductivity and AC breakdown strength – of epoxy composites filled with 30 wt% of micron sized hexagonal boron nitride (h-BN) are discussed in comparison to neat epoxy.
Our 10 tones, six meters long, hyperbaric vessel has been installed at our premises and is now going through final tests before commercial use.

The study involves first the building of an experimental setup where arcs, created between two fixed CuCr25 contacts, were visualized using a high-speed camera in a vacuum demountable chamber.
Superconducting fault current limiters (SFCL) are already in operation in alternative current medium voltage applications and their use in HVDC grids is very promising due to their capability of reducing high short-circuit currents.
Since 2016, SuperGrid Institute’s program 4 has intensely worked on the specification of a test platform with the capability to go up to 40bars of internal pressure and validate subsea node, a SuperGrid Institute concept for offshore meshed networks. Beside its imposing size, the particularity of this platform is that it allows combined testing functions on subsea high-voltage cable systems including water pressure, di
For 40 years, the biannual conference ISH (International Symposium on High Voltage Engineering) has permitted to researchers all around the world to meet and share their research in the high voltage field. The 2017 edition took place from August 28 to September 01 in Buenos Aires, Argentina.
New high-voltage power electronic converters and facilities for transmission grids tend to have multiple power switches at different floating potentials. Moreover, the trend goes towards the use of power switches with higher operating voltages (up to 10kV), in order to reduce the number of switches by system.
The present paper deals with space charge in alumina filled epoxy resin for HVDC applications.
