PhD Benoît TEZENAS du MONTCEL “Experimental study and modelling of a metal vapor plasma in a vacuum chamber for the development of High-Voltage Circuit Breakers”
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.
Numerical investigations of ReBCO conductors with high limitation electric field for HVDC SFCL
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.
A novel hyperbaric vessel for SuperGrid Institute
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
Participation of SuperGrid to the ISH 2017 Conference
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.
Supplying Power to HV (≥10kV) control and measurement boards: a challenge to overcome
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.
Influence of Electric Field on Space Charge Distribution in Alumina-filled Epoxy Resin for Application in HVDC GIS
The present paper deals with space charge in alumina filled epoxy resin for HVDC applications.
Evolution of the Cathode Spot Distribution in an Axial Magnetic Field Controlled Vacuum Arc at Long Contact Gap
The evolution of the cathode spot distribution is an important aspect of the behavior of vacuum arcs controlled with an axial magnetic field.
Measurement and Analysis of Partial Discharges in HVDC Gas Insulated Substations
The measurement of Partial Discharges (PD) in Gas Insulated Substation (GIS) enables to identify and analyse various types of defects that can result in electrical breakdown.
Effective ionization coefficients and limiting field strength of Fluoronitriles-CO2 mixtures
The density normalized Effective ionization coefficients and critical breakdown electric field of the Heptafluoro-iso-butyronitrile (Fluoronitriles), and Fluoronitriles-CO2 mixture are investigated using the steady state Townsend (SST) experimental setup, over a range of the density normalized critical electric field (E/N) from 200-1066 Td (E is the electric field and N the gas density).
