dc.descriptionThis paper analyzes how the location of surge arresters on distribution lines over mountainous zones affect the lightning-induced voltages in this kind of lines. Four configurations of non-flat terrains representative of the Colombian topography were chosen. The inclusion of the terrain, the return stroke channel, the distribution line and the calculation of lightning-induced voltages were done by means of the finite difference time domain method in Cartesian coordinates in three dimensions (3D-FDTD). It was found that the induced voltages in non-flat terrains are between 2 and 5 times the obtained for flat terrain. For the case of the simulated terrains A, C and D, the induced voltages surpass the normal operating thresholds of the surge arresters. It supposes that surge arresters placed on distribution lines in mountainous zones have additional strengths to those existing in flat terrains. Nevertheless, there is a configuration (B) where the threshold values are not exceeded.en-US
dc.descriptionEste artículo analiza cómo la ubicación de descargadores de sobretensión, en líneas de distribución sobre zonas montañosas, afecta las tensiones inducidas que se presentan en estas líneas a causa de rayos. Se consideraron cuatro configuraciones de terreno no plano, que son representativas de la topografía colombiana. La inclusión del terreno, el canal de la descarga, la línea de distribución y el cálculo de las tensiones inducidas, se realizó por medio del método de diferencias finitas en el dominio del tiempo en coordenadas cartesianas en tres dimensiones. Se encontró que las tensiones inducidas en terrenos no planos están entre 2 a 5 veces las que se obtienen para líneas sobre terrenos planos. En el caso de los terrenos A, C y D simulados, las tensiones inducidas superaron los umbrales de operación normales de los descargadores de sobretensión, lo que supone que aquellos ubicados en líneas de distribución en zonas de montaña tienen esfuerzos adicionales a los que se presentan en terreno plano. Sin embargo, hay una configuración (la B), donde no se superan dichos umbrales.es-ES
