An automatic system to locate phase-to-ground faults in medium voltage cable networks based on the wavelet analysis of high-frequency signals

The paper presents a microcontroller-based automatic system that applies the continuous wavelet analysis to the measured fault-originated electromagnetic transients in order to locate phase-to-ground faults in power distribution networks composed by coaxia ...

Frequency-domain analysis of ground electrodes buried in an ionized soil when subjected to surge currents: A MoM–AOM approach

Keyhan Sheshyekani

A frequency-domain method is proposed for the transient analysis of grounding systems with ionized soil. The method involves two stages. First, the grounding system is transformed into a nonlinear equivalent circuit, in which the frequency-domain circuit p ...

Simulation of epiretinal prostheses - Evaluation of geometrical factors affecting stimulation thresholds

Philippe Renaud, Arnaud Bertsch, Willyan Hasenkamp Carreira, Sri Harsha Kasi Raj, Grégoire Cosendai

Background An accurate understanding of the electrical interaction between retinal prostheses and retinal tissue is important to design effective devices. Previous studies have used modelling approaches to simulate electric fields generated by epiretinal p ...

ITER - Earthing

Damien Fasel, Ugo Siravo, Jonathan Bryan Lister, Philippe Marmillod, Albert Perez, Blaise Marlétaz

Earthing of electrical installations is mainly governed by safety rules. Electromagnetic compatibility also deals with earthing, among other circuit characteristics. Tokamaks are large-scale electrical installations that are known to generate large and low ...

A complete graph effective medium approximation for lattice and continuum percolation

Claudio Grimaldi

In this paper we introduce an effective medium theory that is capable of describing site percolation in both lattice and continuum three-dimensional systems. By exploiting self-consistency with a complete graph or network of identical conductors, the resul ...

VlogSense: Conversational Behavior and Social Attention in YouTube

Daniel Gatica-Perez, Joan Isaac Biel Tres

We introduce the automatic analysis of conversational vlogs (VlogSense, for short) as a new research domain in social media. Conversational vlogs are inherently multimodal, depict natural behavior, and are suitable for large-scale analysis. Given their div ...

Dc bus utilisation in multiphase VSI supplied drives with a composite stator phase number

Drazen Dujic

Multiphase variable-speed drives are typically supplied from a two-level voltage source inverter (VSI). The number of phases of the machine and hence the legs of the inverter can be either a prime or a composite number. Limits of the dc bus utilisation in ...

Dependence of the ac loss on the aspect ratio in a cable in conduit conductor

Pierluigi Bruzzone

The coupling current loss in rectangular superconducting cables is strictly dependent on their aspect ratio, which has an impact on the area linked by the field variation and consequently on the currents induced between strands. The relation between the ac ...

Analysis of Output Current-Ripple RMS in Multiphase Drives Using Polygon Approach

Drazen Dujic

Multiphase variable-speed drives, supplied from two level voltage-source inverters (VSIs), are currently considered for a number of industrial applications. Although various multiphase pulsewidth-modulated (PWM) schemes had been recently developed, very li ...
