Análisis del funcionamiento de un descargador tipo rayo para sobretensiones de líneas de transmisiones eléctricas

Abstract

The study addresses the protection of transmission lines against transient events induced by lightning strikes, evaluating the effectiveness of a lightning-type surge arrester as a solution to mitigate the effects of such surges on electrical infrastructure. The methodology employed utilized ATP Draw software, an advanced simulation tool that enabled the modeling of the arrester's behavior under diverse conditions, analyzing its interaction with the components of the electrical system. Through detailed simulations, transient events at critical points of the network were assessed, highlighting the device's high effectiveness in reducing lightning induced overvoltages. However, the analysis emphasizes the need to complement this solution with additional protection strategies to ensure the system's long-term reliability and efficiency. This integrated approach, combining advanced protective devices and a robust network design, enhances the resilience of the electrical system, ensuring the protection of equipment and operational continuity.
