Procedimentos realizados em manutenções de subestações de média e baixa tensão

Abstract

The work addresses the procedures performed in electrical substation maintenance, encompassing several relevant topics. Highlighting the importance of preventive and periodic maintenance to extend the useful life of equipment and avoid system failures. A detailed explanation of the equipment present in a power substation is presented, including transformers, circuit breakers, disconnect switches, insulation muffles and lightning rods. Each piece of equipment is discussed in terms of its function, importance, and associated testing procedures. Practical examples of tests carried out in the field by the author are presented, providing real and reliable data. The results of the insulation resistance, contact resistance and turns ratio tests are discussed, demonstrating the integrity and efficiency of the analyzed equipment. These results support the importance of maintenance procedures and tests performed to ensure the safe and reliable operation of electrical substations. In summary, this TCC comprehensively addresses the procedures performed in electrical substation maintenance. It is expected that this work will contribute to the improvement of maintenance procedures in electrical substations, promoting the safety and reliability of the electrical power system.
