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 ...

Electromagnetic Field Coupling to Transmission Lines: A Model for the Risers

Farhad Rachidi-Haeri, Gaspard Lugrin, Nicolas Mora Parra

In this paper, an improved model of the vertical risers of a transmission line is proposed and validated. The proposed improved model, which can be readily implemented in the frame of a classical transmission line formulation, provides accurate results at ...
