Summary: Electric power distribution systems play a crucial role in social welfare and economic development, providing the foundation for essential services and business sustainability. However, many components of these systems face technological obsolescence, contributing to power supply failures at critical moments. This scenario is further exacerbated in Brazil due to the predominance of bare conductors in its distribution networks, making them susceptible to failures caused by external agents. However, it is observed that these electrical system failures may take time to be detected and located, resulting in deteriorating electrical energy quality, specifically in system interruption time, which increases the financial compensations paid by utilities to consumers. To tackle these challenges, this dissertation presents the Fuse Sensor project, developed in partnership with the company SEVEN (Seven Science Systems Ltda), as an innovative solution incorporating Smart Grid concepts and IoT (Internet of Things) technology for faster fault location and repair, thus enabling the improvement of efficiency and reliability of electrical
systems. The Fuse Sensor is designed to meet the present and future needs of the electrical system, focusing on reducing DEC (Duration Equivalent of Interruption per Consumer Unit) and providing significant gains in compensations. The master’s project approach is structured in three distinct stages: in the first stage, the conception and construction of the Fuse Sensor project are presented, along with testing procedures; in the second stage, validations of the Fuse Sensor project are conducted, including a comparison of the effectiveness of LoRa, SigFox, and FSK communication technologies; and finally, in the third stage, an economic analysis is conducted, considering not only the acquisition costs of innovative equipment but also its economic viability for utilities. By addressing these aspects comprehensively, the Fuse Sensor project aims not only to mitigate the repair time
for interruptions in the power supply but also to promote significant improvements in the quality and reliability of the electrical service. Combining technological innovation and detailed economic analysis, the project seeks not only to meet the current demands of the electrical sector but also to pave the way for a more efficient and sustainable future.
