Lightning-induced voltages in power and communication systems are nowadays one of the main causes of power quality and electromagnetic compatibility. In recent years, due to the increasing demand by customers for good quality in the power supply along with ...
Recently, engineering return stroke models were extended to take into account the presence of an elevated strike object, which was modeled as an ideal uniform transmission line. We show in this paper that the current distribution associated with these exte ...
Feasibility studies performed in the last years have shown that the use of the low voltage distribution network can be used for data transmission. The main problem is the possible radiation of electromagnetic field and the disturbances which can affect rad ...

The paper is a contribution to the studies of factors that can affect electric (E) and magnetic (H) fields associated with lightning return strokes to tall structure. Herein, the influence of lightning channel inclination upon vertical E-field and azimutha ...
Power line communication (PLC) is a well-known technique for data transmission over low-voltage power lines. The PLC signals have frequency bandwidth of about 1-30 MHz and they may cause electromagnetic interferences with services operating in the same fre ...
The propagation of the electromagnetic field in fully coated near field optical probes was analyzed. It was proved that these structures allow nonzero modal emission of the electromagnetic field through a 60-nm thick metallic layer. It was also found that ...
In this paper, an analysis of electric and magnetic fields radiated by lightning first and subsequent return strokes to tall towers is presented. The contributions of the various components of the fields, namely, static, induction, and radiation for the el ...
The analysis of the dynamic behavior of power transmission line and telecommunication towers is of interest in protection and EMC studies related to lightning. Usually, time-domain surge impedance is used to characterize tower dynamic behavior. The main dr ...
In this study, we present an experimental validation of the transmission line representation of an elevated object struck by lightning. The experimental results are obtained using a reduced-scale model and injected signals with narrow pulse widths (down to ...
