Methods for Partial Discharge Calibration in Gas-Insulated Substations for HVDC Power Grids and Charge Evaluation Uncertainty
This paper shows a Partial Discharge calibration method for very-high frequency magnetic and electric sensors in GIS.
The aims of this work were to study its behaviour and to compare its performances with other measuring methods.
SuperGrid Institute, RTE and MasterGrid signed a promising partnership agreement for the decarbonisation of the electricity industry!
A partnership agreement to find an alternative to the use of SF6 gas (most potent greenhouse gas) in existing electrical installations.
Characterization and modelling of interface between Epoxy Resin materials and different gases for HVDC GIS cable termination development
GIS cable terminations present a complexity of geometry and material assembly that makes their design challenging.
DC time constants in different parts are computed and presented in this paper for a cable GIS fluid filled connection assembly.
New DC interrupting principle adjusts the injected counter current to use the vacuum bottle’s interruption capability under optimum conditions.
