Efficient Method Based on the Electromagnetic Time Reversal to Locate Faults in Power Network

Mario Paolone, Farhad Rachidi-Haeri, Reza Razzaghi, Gaspard Lugrin, Hossein Mahmoudimanesh

A time reversal process for determining a fault location in an electrical power network comprising multi-conductor lines, comprises measuring at an observation point located anywhere along one of the multi-conductor lines, for each of the conductors of the ...

Lightning Electromagnetic Fields and Their Induced Currents on Buried Cables. Part II: The Effect of a Horizontally Stratified Ground

Mario Paolone, Keyhan Sheshyekani

We use a finite element method (FEM) to evaluate the effect of a horizontally stratified two-layer ground on underground lightning electromagnetic fields and their induced currents on the shield of buried cables. It is shown that the azimuthal component of ...

On the Use of Electromagnetic Time Reversal to Locate Faults in Series-Compensated Transmission Lines

Mario Paolone, Reza Razzaghi, Gaspard Lugrin

The paper focuses on the extension to series-compensated multiconductor transmission lines of a new fault location method based on the Electromagnetic Time Reversal (EMTR) theory. The applicability of the EMTR theory to locate faults is first summarized. T ...

An Efficient Method Based on the Electromagnetic Time Reversal to Locate Faults in Power Networks

Mario Paolone, Carlos Alberto Romero Romero, Reza Razzaghi, Gaspard Lugrin

This paper presents a new method based on the electromagnetic time-reversal (EMTR) theory for locating faults in power networks. The applicability of the EMTR technique to locate faults is first discussed. Using the classical transmission-line equations in ...

Impact localisation with FBG for a self-healing carbon fibre composite structure

Véronique Michaud, Eva Kirkby

We demonstrated the localisation of impacts in orthotropic carbon fibre reinforced polymer (CFRP) composite materials to within a few centimetres, using a sparse array of fibre Bragg grating (FBG) sensors. This type of sensor is easily embedded in composit ...

Effect of Groundwater on Landslide Triggering

Cornelia Sara Brönnimann

Landslides belong to the most important natural hazards in all mountainous regions. It is wellknown that water is one of the major triggers of landslides. Numerous landslide studies discuss different effects that water may have on slope stability: decreasi ...

Direct localised measurement of electrical resistivity profile in rat and embryonic chick retinas using a microprobe

Philippe Renaud, Arnaud Bertsch, Harald Van Lintel, Robert Meissner, Sri Harsha Kasi Raj

We report an alternative technique to perform a direct and local measurement of electrical resistivities in a layered retinal tissue. Information on resistivity changes along the depth in a retina is important for modelling retinal stimulation by retinal p ...

Axisymetrical infiltration in soil imaged by non-invasive electrical resistivimetry

Jordi Batlle-Aguilar

To progress in the monitoring and understanding of soil water processes, geophysical methods can be helpful because they are non invasive and as such do not disturb either the structure or the water dynamics of the soil. In this study we attempt to image w ...

Continuous-wavelet transform for fault location in distribution power networks: Definition of mother wavelets inferred from fault originated transients

Mario Paolone

The paper presents a fault location procedure for distribution networks based on the wavelet analysis of the fault-generated traveling waves. In particular, the proposed procedure implements the continuous wavelet analysis applied to the voltage waveforms ...
