The protection systems of an Electrical Power System (EPS) equipment play a fundamental role in ensuring the reliability and security of the network. The study of protection and selectivity assumes great importance in establishing the settings of the devices that operate in the system, aiming to preserve the equipment in case of failures, minimize the affected area, and reduce service interruption time. In this paper, the operation of the differential protection on PCH Mantovilis is presented, along with its variables, described mathematically and through graphics. When applied in a real scenario, the effectiveness of this protection it was evaluated, taking into consideration the system requirements. The operability of the protection systems was confirmed through the results of tests performed on the SEL700G device, using a specific equipment for this purpose, the CE6006 test set.
