Electromagnetic Time Reversal Applied to Fault Location: On the Properties of Back-Injected Signals

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

By using the electromagnetic time reversal (EMTR) theory, the paper studies its properties in order to derive a new fault location method to be used in power networks. It is shown that, in the reversed-time stage, the current signal observed at the true fa ...

LMA Observation of Upward Flashes at Santis Tower: Preliminary Results

Farhad Rachidi-Haeri, Marcos Rubinstein, Mohammad Azadifar, Amirhossein Mostajabi

Lightning striking tall towers is mainly of the upward lightning type, which is characterized by the absence of a first return stroke and the presence of an initial continuous current (ICC) with or without superimposed pulses. The Santis Tower is 124 m tal ...

Study of the Propagation of Common Mode IEMI Signals Through Concrete Walls

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

In this paper, a model to analyze the propagation of intentional electromagnetic interferences disturbances along penetrating conductors into concrete walls is proposed. The model is based on the transmission line theory and considers the attenuation of th ...

Generalized Telegrapher's Equations for Buried Curved Wires

Farhad Rachidi-Haeri, Damir Cavka

The paper deals with the calculation of transient currents and voltages along curved wire structures buried in a lossy ground using the generalized Telegrapher's equations. The influence of a lossy half space is taken into account by the simplified reflect ...

Modeling of Different Charge Transfer Modes in Upward Flashes Constrained by Simultaneously Measured Currents and Fields

Farhad Rachidi-Haeri, Marcos Rubinstein, Davide Pavanello, Mario Paolone, Mohammad Azadifar, Lixia He, Qi Li

The purpose of the paper is to investigate charge transfer modes in upward lightning flashes by means of numerical simulation constrained by concurrent observations of electromagnetic fields and currents. In particular, we focus on different types of pulse ...

An Analysis of Lightning Activity in the Säntis Region through the Big Hiatus in Global Warming

Farhad Rachidi-Haeri, Marcos Rubinstein, Aleksandr Smorgonskii, Mohammad Azadifar, Amirhossein Mostajabi

The response of local lightning to local surface temperature is examined near the Säntis mountain (2502 m ASL) in the eastern Swiss Alps during the first of the two hiatuses in global warming covering the time periods 1940-1972 and 1998-2014. The mountain ...

An Analysis of the Distribution of Inter-Flash Time Intervals in the Area of the Santis Tower

Farhad Rachidi-Haeri, Marcos Rubinstein, Antonio Sunjerga

In this paper we analyzed the time intervals between flashes in the Santis area for three highly active storms and also for a period of 21 months. The overall distributions of inter-flash time interval are found to be very similar and reasonably represente ...
