Item Propriedades Elétricas das Buchas de Isolamento das Subestações de Alta Tensão: Um Estudo das Novas Tecnologias - Materiais(INSTITUTO DE TECNOLOGIA, 2013) DUARTE NETO, Luiz Pinheiro; CIRINO, Weverson dos Santos; HOLANDA, Ubiratan Bezerra.; Prof. Dr. Carlos Tavares da Costa JúniorThe use of electrical bushings is very important in the design of a substation and is a key part of high voltage equipment. The article provides a detailed study of the main properties of high voltage bushings and their characteristics, as well as new technologies being developed for the design of more reliable and less fault-prone electrical bushings.Item Optimización del proceso de montaje de componentes SMD usando algoritmo genético multiobjetivo en la industria(INSTITUTO DE TECNOLOGIA, 2014) CIRINO, Weverson dos Santos; MUSTAFE, Nadime; REIS, Ana; CASTRO, Anderson; BEZERRA, Ubiratan Holanda; Professora Dra. Fernanda Souza do NascimentoThe article proposes the optimization of the assembly sequence of SMD components on printed circuit boards using a multi-objective genetic algorithm (NSGA-II). The study was conducted in an electronics industry at the Manaus Industrial Hub, showing that the proposed algorithm outperformed the traditional machine inserter optimizer, reducing assembly time by 6 seconds per board and increasing productivity by 30%. The results highlight the effectiveness of NSGA-II in solving complex industrial optimization problems.Item Sistema de Controle de Temperatura Digital como Ferramenta para a Eficiência Energética na Indústria(INSTITUTO DE TECNOLOGIA, 2014) CIRINO, Weverson dos Santos; MUSTAFE, Nadime; REIS, Ana; CASTRO, Anderson; TANAKA, Gerdson; TOSTES, Maria Emília; BEZERRA, Ubiratan Holanda; TOSTES, Maria Emília; BEZERRA, Ubiratan HolandaThe study presents the implementation of a digital temperature control system based on hysteresis to optimize energy efficiency in a plastic injection industry. The results demonstrate a significant reduction in energy consumption, with annual savings of approximately R$ 47,166.86, along with improvements in temperature stability, reduced maintenance costs, and extended equipment lifespan. The system proved economically viable, with a return on investment in 39 days.Item Aplicação de Filtro Harmônico em Sistemas Elétricos de Baixa Tensão Utilizando Lógica Fuzzy(Universidade Federal do Pará, 2010) CIRINO, Weverson dos Santos; COSTA JUNIOR, Carlos Tavares daThis work presents a solution to minimize harmonic distortion in low-voltage electrical systems through the application of passive harmonic filters and the use of fuzzy logic. The proposed algorithm detects and calculates the frequencies at which the Total Harmonic Distortion (THD) value is elevated, comparing it with a normative index. Once the need for filter application is identified, the algorithm designs the passive filter, chosen for its ease of installation and low cost. The algorithm also recalculates the THD after filter application, using fuzzy logic to classify the final result.
