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 ...
This paper presents an analysis of lightning return strokes to tall structures. The interaction of lightning with a tall structure is modeled using the antenna theory. The finite ground conductivity as well as the buried grounding system of the tall struct ...
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 ...
New general expressions relating lightning return stroke currents and far radiated electric and magnetic fields are proposed, taking into account the effect of an elevated strike object, whose presence is included as an extension to the transmission line ( ...
Measurements of return stroke currents on instrumented towers reveal the existence of reflections at the tower bottom and top. In the paper, the effects of the reflections on both measured currents and the original lightning electromagnetic fields are disc ...
In this paper, we present a review of theoretical methods to compute lightning induced currents and voltages on buried cables. The evaluation of such induced disturbances requires the calculation of the electric field produced by lightning along the cable ...
Presents an analysis in the time and frequency domains of the electromagnetic field originated by negative lightning return strokes, calculated at ground level. The analysis is performed on the basis of the transmission line model modified by the authors, ...
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 ...
Lightning currents and electromagnetic fields associated with return strokes to elevated strike objects The aim of this thesis is the modeling of lightning return strokes impacting elevated strike objects such as towers. The theoretical and experimental wo ...
The knowledge of lightning current parameters comes essentially from direct measurements obtained using instrumented towers or triggered lightning, and from measurements of lightning electromagnetic fields assuming empirical or theoretical relations betwee ...
