“…The 1.5 factor is an approximation which accounts for the turnup in the insulation volt-time curve, as the induced voltages are assumed to have much shorter duration waveforms than the standard 1.2/50 s test waveform. However, some authors (e.g., [18]) propose that a factor of 1.2 instead of 1.5 would lead to more realistic results. Indeed, the 1.5 factor seems to be derived from the assumption of perfectly conducting soil, which leads to very short waveforms.…”

“…Se presentó, por primera vez a nivel mundial, este aporte (Silveira, 2008). Y en (Pérez, 2006) los 3 principales aportes se realizaron en: a) descripción de los diferentes efectos de los parámetros del rayo y de la línea sobre las tensiones inducidas, b) identificación de los parámetros más influyentes en las tensiones inducidas y c) una ecuación sencilla para calcular tensiones inducidas máximas con errores menores que las ecuaciones existentes y así lograr aplicaciones para ingeniería eléctrica (Conti, 2010).…”

Artículo de posesión para el ingreso como miembro de número a la Academia Colombiana de Ciencias Exactas, Físicas y Naturales el 26 de julio de 2017 ResumenEste artículo sobre la investigación del fenómeno del rayo ha sido elaborado para la posesión como Miembro de Número de la Academia Colombina de Ciencias Exactas, Físicas y Naturales. El fenómeno natural ha sido investigado sistemáticamente en Colombia desde hace aproximadamente cuatro décadas motivado por la curiosidad científica para comprender la alta mortalidad de sistemas, equipos y de personas. Con base en el desarrollo de una hipótesis de investigación se fueron confrontando sus resultados con la realidad concreta, mediante el método científico inductivo y la categoría conceptual de un trabajo interdisciplinario con vínculos dialecticos y la intersección e integración de saberes como la física, las matemáticas, la química, la biología, la historia, la literatura y la psicología social. Con los resultados de investigación se ha logrado aportar nuevo conocimiento del fenómeno en el concierto mundial con libros, artículos científicos, patentes, innovaciones tecnológicas para aplicaciones en protección contra rayos, normas y reglamentos técnicos y apropiación social de la ciencia. Este articulo presenta los logros científicos y tecnológicos realizados en Colombia en el campo de las descargas eléctricas atmosféricas, y propone, basado en las condiciones específicas intertropicales, los focos de investigación de interés para el país en el futuro. © 2017.

The interdisciplinarity of lightning AbstractThis paper on the research of the lightning phenomenon has been elaborated for the author's possession as a Member of Number of the Colombian Academy of Exact, Physical and Natural Sciences. This phenomenon has been systematically investigated in Colombia in the last four decades or so, motivated by the scientific curiosity to understand the high incidence of damage to systems and equipment, as well as mortality of people. Based on the development of a research hypothesis, the results were compared with concrete reality by using the scientific inductive method and the interdisciplinary work with dialectical links and the intersection and integration of knowledge from Physics, Mathematics, Chemistry, Biology, History, Literature and Social Psychology. The results have contributed with new knowledge in the world concert with research books, papers, patents and technological innovations for applications in lightning protection, technical standards, technical regulations and social appropriation of the science. This article presents the scientific and technological achievements made in Colombia in the field of atmospheric electric discharges, and proposes, based on specific intertropical conditions, the research focus of interest to the country in the future. © 2017.

“…Most voltages induced on a distribution line by flashes that terminate near a line are less than 300 kV [2]. With respect to traditional methodologies for the study of lightning effect on distribution feeders, those are usually carried out by digital simulation, which reproduce the transient overvoltages at the insulators and by using manual processing they are developed [1]- [13].…”
