Study of Turn-to-Turn Electrical Breakdown for Superconducting Fault Current Limiter Applications

2018-11-06T16:01:51+00:00November 2nd, 2018|High Voltage Substation Equipment, Publications|

The rational insulation design of a resistive superconducting fault current limiter (r-SCFCL) requires data gathered from experimental setups representative of the final apparatus. Therefore, an experimental study was performed to characterize the electrical breakdown (BD) of liquid nitrogen (LN2) in the peculiar conditions of a quenching superconducting device.

Measurement and Analysis of SiC-MOSFET threshold voltage shift

2018-10-04T13:19:11+00:00October 4th, 2018|Conference, Power Electronics & Converters|

Gate-oxide technology weakness is a main reliability issue of Silicon Carbide MOSFET transistors. The threshold voltage shift is a critical phenomenon that addresses the reliability of industrial power applications. It is important to have a better understanding of the phenomena implied in the gate threshold voltage shift. In this context, HTGB test is proposed and the resulting gate oxide stress is studied and discussed in this paper.

PhD Etienne OUSS “Characterization of Partial Discharges and Defect Identification in High-Voltage Direct Current GIS”

2018-10-08T14:41:48+00:00September 25th, 2018|All, High Voltage Substation Equipment, Phd|

This thesis aimed to characterize partial discharges in DC gas-insulated substations, and to develop an automatic defect identification tool. The first step of this work was the development of a partial discharge measuring bench. The complete study has been performed in a GIS section, so that the results can be directly applied to industrial equipment.

Repetitive short-circuit measurement on SiC MOSFET

2018-09-07T16:41:28+00:00September 7th, 2018|Conference, Power Electronics & Converters|

Robustness study for the 1.7 kV SiC MOSFET is presented. After evaluation of the critical energy required for failure, devices were submitted to repetitive short-circuits conditions.

Models of AC and DC cable systems for technical and economic evaluation of offshore wind farm connection

2018-09-03T10:30:20+00:00September 3rd, 2018|High Voltage Substation Equipment, HVDC Cable Systems, Publications|

Accurate cable modeling is a recurrent issue for electric architecture evaluation and design, especially in specific contexts, like offshore wind farms. This paper proposes optimal analytical cable models for the technical and economic assessment of offshore wind generation systems.
