Overhead Power Lines are the prevailing facilities to carry electric energy across big distances. They have experimented a great development during the last century due the economic expansion, and they have become essential assets for the countries. Although during this time they have reached an outstanding technical status, there are different phenomena, such as short-circuits and heavy weather conditions, which can cause the failure of these facilities. Simulation constitutes a powerful tool to minimize and analyze these failures. This paper presents two applications of a multiphysic algorithm developed by the authors that is able to perform electro-thermal dynamic simulations of overhead power lines. The first application shows a transient evolution for a given overhead power line during an open-close sequence due a persistent short-circuit. Then, a long-time simulation is performed considering the load curve and the environmental temperature variations during a given day. And lastly, a collapse of a conductor when a tree hits the overhead power line is shown.
