Currently, computational power has replaced these with long data lists, the result of solving equation systems with numerical methods. In this sense, diagrams have been relegated to an academic background topic that, although theoretically explained, is not used in practice. This fact may work against the understanding of the complex behavior of electrical power systems by students. This paper proposes a modification of the classic Perrine-Baum diagram construction to allow both a more practical representation and a better understanding of the behavior of a high-voltage transmission line under different load levels. A tool capable of evaluating the moment in time when demand exceeds the line's carrying capacity is also introduced. In addition, the impact of this tool on the learning process is evaluated.
