Operação e manutenção de equipamentos em subestação de transmissão

Abstract

The operation of the main equipment installed in a power transmission substation and the best way that the transmitters work to keep this equipment in the electrical system, operating safely and avoiding failures. Substations that have operated for many years, often need a revitalization process to modernize themselves, since their respective equipment is worn out due to operating time. However, while the entire substation is not fully renovated, the equipment must continue in operation under the supervision of a professional for preventive and corrective maintenance when necessary. Finally, when the revitalization process is about to be completed, end-of-life equipment will be completely shut down when new equipment will be purchased to replace the old ones. This work addresses the inspections (thermographic and visual) that must be carried out on the equipment and the maintenance (preventive, corrective and predictive) with the objective of approaching the practical experience of substation maintenance. Finally, the minimum activities and the frequency of each equipment for the maintenance plan provided by ANEEL are presented and discussed in the analysis of the work. Keywords: Electrical Equipment, Operation and Maintenance of Substations.
