Locating lightning strikes and flashovers along overhead power transmission lines using electromagnetic time reversal

Mario Paolone, Gianluca Antonini, Reza Razzaghi, Keyhan Sheshyekani, Marco Scatena

The paper presents a method to identify the location of direct lightning strikes to overhead transmission lines and potential subsequent flashover(s). The method is based on the electromagnetic time reversal theory and relies on the use of a single measure ...

A Full-Scale Experimental Validation of Electromagnetic Time Reversal Applied to Locate Disturbances in Overhead Power Distribution Lines

Mario Paolone, Farhad Rachidi-Haeri, Marcos Rubinstein, Zhaoyang Wang, Reza Razzaghi

Electromagnetic time reversal (EMTR) has emerged as a promising technique to locate disturbances in power grids, thanks to its location accuracy and robustness against parameters uncertainties. Furthermore, in a reflective medium, like the one of a power n ...

Characteristics of Upward Lightning Flashes

Mohammad Azadifar

In addition to the general aims of lightning research such as lightning physics and meteorology, the study of upward lightning is of particular importance in protection of tall objects such as wind turbines and telecommunication towers. It also helps us in ...

Formulation of the Field-to-Transmission Line Coupling Equations in Terms of Scalar and Vector Potentials

Farhad Rachidi-Haeri, Marcos Rubinstein

More than 60 years ago, Prof. S. Rusck introduced a coupling model to take into account the interaction of lightning-generated electromagnetic fields with overhead power transmission and distribution lines. The model which assumes that the ground is perfec ...

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, ...

Electromagnetic Fields of a Lightning Return Stroke in Presence of a Stratified Ground

Farhad Rachidi-Haeri, Marcos Rubinstein, Abdenabi Mimouni

We present an analysis of the nearby electromagnetic fields generated by lightning discharges in the presence of a horizontally stratified, two-layer ground. To the best of our knowledge, this is the first time the effect of ground stratification on underg ...

On the Location of Lightning Discharges Using Time Reversal of Electromagnetic Fields

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

In this paper, we discuss the use of the electromagnetic time reversal (EMTR) method to locate lightning strikes. After a brief description of the EMTR and its application to lightning location, we mathematically demonstrate that the time-of-arrival method ...
