These kinds of phenomena have dangerous consequences, therefore studies concerning the effects of lightning are crucial. The normal operation of transmission and distribution systems is greatly affected by lightning, which is one of the major causes of power interruptions: direct or nearby indirect strikes can cause flashovers in overhead transmission and distribution lines, resulting in over voltages on the line conductors. Contributions to this Special Issue have mainly focused on modelling lightning activity, investigating physical causes, and discussing and testing mathematical models for the electromagnetic fields associated with lighting phenomena. In this framework, two main topics have emerged: 1) the interaction between lightning phenomena and electrical infrastructures, such as wind turbines and overhead lines; and 2) the computation of lightning electromagnetic fields in the case of particular configuration, considering a negatively charged artificial thunderstorm or considering a complex terrain with arbitrary topographyTechnology: general issuesbicssclightninglightning protection systemwind turbine bladesANSYS workbenchgraphics processing unit (GPU)OpenACC (open accelerators)finite difference time domain (FDTD)lightning magnetic fieldselectromagnetic fieldanalytical formulacorona dischargelightning protectionelectromagnetic pulselightning-induced voltagesnumerical codesdistribution lineslightning-induced overvoltagesgrounding modelingsoil resistivityartificial thunderstorm cellupward streamer dischargeselectromagnetic radiation spectrumwavelettransmission line monitoring systemmodel elementsimulationcoronalightning surgeoverhead linetransient calculationTechnology: general issuesBrignone Massimoedt1325353Mestriner DanieleedtBrignone MassimoothMestriner DanieleothBOOK9910557485103321Lightning Modeling and Its Effects on Electric Infrastructures3036789UNINA
