Locating transient disturbance sources and modelling their interaction with transmission lines : use of electromagnetic time reversal and asymptotic theory

Gaspard Lugrin

This thesis deals with the application of electromagnetic time reversal to locating transient disturbance sources and the use of the asymptotic theory for the modelling of their interaction with transmission lines. We demonstrate that the time-of-arrival, ...

Assessment of the Influence of Losses on the Performance of the Electromagnetic Time Reversal Fault Location Method

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

Electromagnetic time reversal (EMTR) has been shown to be an efficient method for locating faults in AC and DC power grids. In the available literature, the back-propagation medium has been considered to have identical losses as the direct-time medium. How ...

On the vulnerability Analysis against IEMI

Farhad Rachidi-Haeri, Marcos Rubinstein, Sidi-Rachid Cherkaoui, Nicolas Mora Parra, Gaspard Lugrin

Vulnerability is estimated in terms of the effects that IEMI may induce to the services provided by the facility under study. We estimate the vulnerability by considering three variables: the likelihood, the risk, and the hardness. The different parameters ...
