RESUMO:

The Electric Power System model introduced in Brazil in the late 1990s produced a scenario with a high regulation level. The Agência Nacional de Energia Elétrica (ANEEL) creation and its rules force the agents involved in that system to always seek the low tariffs with a high quality level of service and product quality. The requirements imposed on Brazilian Power Utilities result in the development of processes that allow a continuous improvement. Nevertheless, these strategies are not always sufficient to ensure good quality indicators. Many times, the processes do not hold a perfect synchrony to the point of avoiding execution failures. Other times, the failures are not in the processes, but in the equipment that are objective of the existence of the processes. As an example the preventive maintenance schedules that are developed in certain equipment of a Substation. Another example, unscheduled failures to be corrected is necessary that the correct information, scroll through the channels of communication to quickly and accurately reaching those responsible for maintenance. Correct information does not always reach the department quickly and accurately, but it is stored and cataloged for future analysis. This work aimed to reduce the DEC (Equivalent Duration of Interruption per Consumer Unit) indicator, improvement in maintenance planning and increase in the electrical installations’ s safety level in a substation. By building an embedded system designed to monitor the main internal components of a circuit breaker. With the results achieved, it is concluded that the device provided in the project meets the objectives imposed, being able to perform its functions with speed and assertiveness in the data generated. The integration of this equipment into the circuit-breakers will allow anticipating the failures making the electrical system more reliable and safe
