Epoxy composite with hBN fillers compatible with industrial application in electrical equipment
A synergetic effect between hBN and alumina has been observed regarding thermal and electrical properties. A 500% increase in the thermal conductivity could be achieved with a limited impact on viscosity increase.
DC Leakage Current Measurement Comparison between SF6 and Fluoronitrile/CO2 Gas Mixture
One of the possible SF6 alternatives that emerged in recent times is a fluoronitrile (FN), NovecTM 4710, based mixture.
Production of Graphite During the Extinguishing Arc with New SF6 Alternative Gases
Using Gibbs free energy method, a theoretical study has been conducted on SF6 replacement candidates listed above.
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.
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.
