Partial Discharge Defect Recognition Tool For MV/HV DC Equipment
Partial discharges measurement is the most common technique to identify defects and the corresponding risks for Medium/High Voltage equipment.
SuperGrid Institute’s DC circuit breaker goes public at the IEEE General Meeting in Denver
We are proud to be revealing our 525kV DC circuit breaker at the IEEE Power & Energy Society General Meeting.
Partial discharge measurement in DC GIS: comparison between conventional and UHF methods
The aim of this paper is to investigate the partial discharge signals recorded with both conventional and UHF methods in DC voltage.
Simulation methodology for HVDC cable accessories: focus on oscillating polarity reversal and fast transient overvoltages
The aim of this paper is to propose a time decoupled simulation method to compute the electric field in case of OPR and S/IMP without losing in result accuracy.
Réseaux epoxy-liquides ioniques : relations structure/propriétés électriques

Dielectric testing of gas insulated HVDC systems: CIGRE Technical Brochure 842 published with SuperGrid Institute’s input
Thanks to our recognised expertise in this field, we were involved in producing the CIGRE Technical Brochure 842 “Dielectric testing of gas insulated HVDC systems”.
Study of high current magnetron impulse discharge
High current density magnetron impulse discharge (HCDMID) could be used in numerous applications like surface deposition, etching...
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.
