Electromagnetic time reversal for online partial discharge location in power cables: Influence of interfering reflections from grid components
Marcos Rubinstein, Farhad Rachidi-Haeri
In online single-sided partial discharge (PD) location, the measured PD reflection patterns are affected by the characteristics of all the components of the associated power network. This paper analyses the performance of a PD location method based on elec ...
2024Modeling, Optimization and Design of High Power Medium Frequency Transformers
Nowadays, direct current (DC) technology is increasing its presence in alternating current (AC) power systems. This trend is enabled by the progress in energy conversion through semiconductor devices and power electronics. Therefore, it is possible to imag ...
EPFL2023Time-Domain Integration of Broadband Terahertz Pulses via Tapered Two-Wire Waveguide
In this work, we report on the implementation of a time-domain integrator device operating on arbitrary broadband Terahertz (THz) pulses. This analog signal-processing functionality is implemented by employing a two-wire waveguide (TWWG) variant, based on ...
New York2023Metal-wire-embedded alumina insulating material using micro- and nanoscale 3D printing for surface flashover mitigation in a vacuum
A micro- and nanoscale 3D printing technique is applied to fabricate a functional insulating material that mitigates surface discharge in a vacuum based on microscopic electron multipactor suppression. The proposed alumina ceramic insulator design consists ...
2022Development of a large-area, light-weight module using the MALTA monolithic pixel detector
Edoardo Charbon, Francesco Piro, Ashish Sharma
The MALTA pixel chip is a 2 cm x 2 cm large monolithic pixel detector developed in the Tower 180 nm imaging process. The chip contains four CMOS transceiver blocks at its sides which allow chip-to-chip data transfer. The power pads are located mainly at th ...
ELSEVIER2022Optical rotating torque sensor with nano newton-meter resolution based on a hanging torsion wire
Simon Nessim Henein, Etienne Frédéric Gabriel Thalmann, Billy Nussbaumer
This article presents a novel torque measuring setup working in the nano newton-meter range. The central novelty is a long (1 meter range) thin (diameter of a few tens of micrometers) metallic wire used instead of the relatively stiff torsion zone of the s ...
2021Design and Characterization of the Interlayer Joint Between Low-Field Nb3Sn Conductors of a Layer Wound DEMO TF Coil
Pierluigi Bruzzone, Kamil Sedlák, Boris Stepanov, Mithlesh Kumar
In the frame of the conceptual design studies for the Toroidal Field (TF) coils of DEMO, a solution based on a layer-wound magnet, rectangular-shaped Cable-in-Conduit conductors and W&R manufacturing approach, is being developed. The feasibility and perfor ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2021Small scale very high speed slotless permanent magnet motors
This research work has been triggered by an industrial project aimed at modelling and manufacturing a small-scale very high speed motor. Very high speed electrical motors offer the main advantage of reducing the size of a system. Indeed, at constant output ...
