Análise teórico-experimental do melhoramento da malha de aterramento em subestações energizadas aplicando software TecAt Plus 6.2.

Abstract

Grounding systems have an important role, especially when taking into account the safety of living beings, thus requiring a permanent assessment due to the aging of the earth's meshes. In order to simplify the work of the designers, several softwares present computational tools to assist the engineer in the elaboration of these projects, one of them is TecAt Plus 6.2. The simulations were carried out in the TecAt Plus environment, verifying the potential of pitch and touch in a short-circuit situation, in the same way, studies were made to obtain improvements in the grounding system, in order to reduce its resistance and The surface potentials of the same. With the results obtained, it was concluded that two substations did not meet the requirements of the norms, thus an improvement of the earth mesh was made, framing them within the appropriate values.
