“…Interestingly, the second effect is also present -although to a reduced extent -if the building is situated at the opposite side of the line with respect to the lightning channel. Also, the results obtained by using the proposed procedure that involves both a 3D FEM model for the calculation of the LEMP and the solution of the field-to-line coupling equations appear to be consistent with the measurements presented in [9,10] obtained using reduced scale model.…”

“…In [10] the measured voltages on the scale model without buildings have been successfully reproduced by using the LIOV-EMTP code [11][12][13] for the calculation of the voltages induced by lightning return strokes on multiconductor lossy overhead lines. The LEMP-to-line coupling model adopted by the LIOV code is the one proposed by Agrawal et al [14].…”

a b s t r a c tFor the case of urban overhead lines, the presence of nearby buildings is expected to affect the overvoltages induced by nearby cloud-to-ground lightning return strokes. So far, this effect has been seldom taken into account in the literature on the subject. The paper presents a 3D FEM model that calculates the lightning electromagnetic pulse (LEMP) taking into account the presence of a building placed in proximity of the LEMP-coupled overhead line. As a first approximation, all the metallic elements are assumed as perfect conductors, as well as the ground plane. The calculated fields are then introduced in the Agrawal et al. coupling model for the calculation of the induced voltages. The results of a sensitivity analysis carried by varying the model and dimensions of the building, its distance to the line and the position of the lightning stroke location are presented and discussed.

“…Scale models of electrical systems have been a popular tool, especially in the past, to predict power system transients after different types of perturbations [14]. For instance, a 3/100-scale model of an actual wind turbine generation system that has blades with a length of 25 m and a turbine that is 50 m high was considered in [15] for experimental and analytical studies of lightning overvoltages.…”

This paper is concerned with the protection of wind energy systems against the direct effects of lightning. As wind power generation undergoes rapid growth, lightning damages involving wind turbines have come to be regarded as a serious problem. Nevertheless, very few studies exist yet in Portugal regarding lightning protection of wind energy systems using numerical codes. A new case study is presented in this paper, based on a wind turbine with an interconnecting transformer, for the analysis of transient phenomena due to a direct lightning strike to the blade. Comprehensive simulation results are provided by using models of the Restructured Version of the Electro-Magnetic Transients Program (EMTP), and conclusions are duly drawn.

“…Based on a small-scale model experiment, Piantini and Janiszewski [159] and Piantini et al [160] analyzed the effectiveness of surge arresters in terms of the reduction of the induced voltage magnitudes. They showed that the effectiveness of surge arresters depends on different factors.…”

Abstract-This review paper, prepared for this second special issue on lightning of the IEEE TRANSACTIONS ON ELECTROMAGNETIC COMPATIBILITY, summarizes major publications on lightning and lightning protection since the first special issue published in November 1998, i.e., during the last decade. The review is organized in the following five sections: lightning discharge-observations, lightning discharge-modeling, lightning occurrence characteristics/lightning locating systems, lightning electromagnetic pulse and lightning-induced effects, and protection against lightning-induced effects.
