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.
This paper focuses on analytical or semi-analytical calculation techniques to be integrated into a medium frequency transformer optimization process.
This paper presents results carried out on polymeric high voltage direct current (HVDC) model cable. Two aspects are considered: partial discharge (PD) and current measurements, with the aim at investigating possible growth of voids of micrometer size.

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.

In the new electrical grids, series/parallel converters architectures can be considered for medium and high voltage power conversion. Dual Active Bridge (DAB) topology is a serious candidate to be implemented within these converters.
This paper presents an overview of the DC-DC power converters dedicated to HVDC proposing a classification based on their structure.
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.
