Effective Permeability of Multi Air Gap Ferrite Core 3-Phase Medium Frequency Transformer in Isolated DC-DC Converters
This article presents the measurements of the equivalent B(H) and the equivalent magnetic permeability of two three-phase MFT prototypes.
Compliance of a cable-based protection strategy for OHL grids: Analysis and remediation
This paper points out the challenges to overcome when applying a protection strategy based on a non-selective fault clearing philosophy without DC reactors to an overhead line based multi-terminal DC grid.
A novel single-ended fault identification algorithm for full selective protection strategy
We propose a parametric single-ended fault identification algorithm to be used in full selective protection strategy.
A novel single-ended fault identification algorithm for full selective protection strategy
We propose a parametric single-ended fault identification algorithm to be used in full selective protection strategy.
SuperGrid Institute demonstrates the partial discharge behaviour of SF6 subtitute gases which can be used in the future HVDC GIS as part of the PROMOTioN project
SuperGrid Institute will be able to develop an effective partial discharge monitoring system for the future SF6 free high voltage equipment.
Characterization of Partial Discharges Initiated by Protrusion in HVDC Coaxial Geometry
This paper aims at the detection and characterization of partial discharges (PD) in GIS under HVDC constraints in the presence of a protrusion/metallic particle on the high voltage conductor.
Partial Discharge Behavior of Protrusion on High Voltage Conductor in GIS/GIL under High Voltage Direct Current: Comparison of SF6 and SF6 Alternative Gases
Recent studies have demonstrated that fluoronitrile (FN) NovecTM 4710 and fluoroketone (FK) NovecTM 5110 show higher dielectric strength than SF6. These gases can be mixed with a buffer gas such as CO2 and technical air to have suitable dielectric properties for high voltage insulation applications.
A Cryostat platform for SuperGrid Institute
SuperGrid Institute is aiming to test the new superconductive tapes that will be used in future current limiters, as one of the partners involved in the FASTGRID project.
SuperGrid Institute’s vision at the second conference on Power Transmission in Africa (Johannesburg)
This morning, SuperGrid Institute presented at the second conference on Power Transmission in Africa (Johannesburg) its vision on new transmission technologies and architecture, shaping the future grids. With emphasis on the fantastic opportunity that the latest HVDC technologies and solutions represent for a robust and interconnected power system in Africa, able to address major issues linked to energy transition.
