- Lightning effects on distribution transformers and reliability of power distribution systems in Colombia D. Aranguren C. Tovar J. Inampués J. López E. Soto H. Torres Ingeniería lightning tropical zone Power reliability weather reliability model Failure rates of rural power systems are statistically studied based on lightning parameters and a two-state weather model (normal and adverse). Lightning information is matched with geographical coordinates of 251,024 power transformers in a vast area in Central Colombia. An important portion of transformers present failure rates 45 times higher than normal, and very large overhead lines, representing a high portion of the total system, present very high failure rates over 75 times higher than in normal weather conditions. 2015 artículo científico 0120-5609 https://www.redalyc.org/articulo.oa?id=64342611005 en http://www.redalyc.org/revista.oa?id=643 Ingeniería e Investigación application/pdf Universidad Nacional de Colombia Ingeniería e Investigación (Colombia) Num.1 Vol.35
