Objectives: An important field of study concerning power grids is the analysis of different incidents that are taking place in the grid. There are various reasons for such incidents. Realizing the cause of failures and finding solutions to prevent their recurrence can be of great help in grid development planning and also for reducing damages caused by such failures. Methods/Analysis: This paper addresses an incident that took place in a 63/20 KV substation. First we overview the substation and its installed equipment in order to have a comprehensive investigation on the failure and its cause. In the following, simulation process based on available data is described. Findings: We address the failure and how it happened, focusing on the factors intensifying it. Novelty/Improvement: A method is proposed to prevent the recurrence of such failures.
