Sistema remoto de ensaios de rotina em transformadores em subestação abrigada com geração de relatório no Excel

Abstract

This work was done with the aim of automating the tests of transformers in substations, allowing the control of the measurement without the need of an operator inside the substations and reducing the time of complete preventive maintenance. The work came with the intention of becoming fast, easier to control and more secure because it is a high risk service. The main component is an Arduino MEGA microcontroller. It controls a prototype connection with a control interface, the measurement modules and selecting results for the user through Excel. The switching between measurement modules and the transformer busbar is performed by relay, some of them with a more specific manufacturing to operate with insulation superior higher than 15 kV. The innovation of this project is the optimization of the tests on transformers when it is already in use ans whithout the need of moving it or hire technicians to do the service. Besides showing the data in organized form in Excel, making it possible to generate the database and adaptations for other report templates.
