“…The test considering three (3) FIs installed in the feeder is illustrated in figure 5. A comparison between figures 4 and 5 shows that, the found solution uses a point out of the main trunk: branch 3102 (or 3104-3102), which would not be possible according to some methodologies, such as the one presented in [4]. To the cases with 4, 5 and 6 FIs, some allocations are out of the main trunk, for 5 and 6 FIs, 2 of them are allocated in branches.…”

 Distribution systems are affected by faults that may lead to service interruption, which is inconvenient for the consumers and increases the refund costs payed by the company. Optimizing the allocation of fault indicators devices (FIs) is a promising alternative to improve the energy quality. Using FIs reduce the team`s average displacement time to the fault(s) location, which implies reduction on the Equivalent Interruption Duration per Consumer Unit (DEC) indicator. Since the indiscriminate use of FIs is prohibitive, this paper presents the implementation of the metaheuristic routine Variable Neighborhood Search (VNS)to determinate optimized locations to install the FIs, aiming DEC reduction. The results, collected from a real feeder, confirm the proposed methodology`s efficiency.

“…On [4] it is proposed the FIs allocation based on Genetic Algorithm (GA). The GA's implementation adopts a fitness function that considers the load distribution, the users number and the distance to other devices capable of detecting faults (including protection devices).…”

“…No Brasil, os indicadores de falta ganharam importância devido à grande extensão de alimentadores de distribuição, construídos para atendimento de unidades consumidoras situadas em zonas rurais, o que dificulta a inspeção da rede para localização do ponto defeituoso pelas equipes de manutenção (USIDA, 2011).…”

Through the R&D program ANEEL -National Electric Energy Agency, a fault circuit indicator (FCI) was developed for medium voltage power distribution networks. As for any project financed by this program, innovation is essential. HartBR team, in partnership with the Energisa Group, designed the equipment and, after 24 months, its whole development was carried out in Brazil. New concepts and technologies were deployed, such as the adoption of a self-power system, without using batteries and based on current transformers with a nanocrystalline core, integrated communication through 900Mhz radio, using IoT technology, and a simple installation system, which uses the conventional cutouts, already installed in the power networks. There was also a research and development work on an engineering polymer for injection of plastic parts. A computerized system was also developed, making possible the integration of the devices with the power utility's supervisory systems, performing the conversion of protocols, transparently to operators. The project reached an innovative equipment, which can be applied in all medium voltage classes, aiming a worldwide certification through type tests and with low production costs. This work describes the stages of the project, the technical analysis of the available technologies and their choices, as well as the results of laboratory and field tests. The R&D program of ANEEL was essential for developing national technology, jobs generation, improvements in the quality metrics for utilities and, consequently, improvement in the population's life quality.
