Item Estimativa da incerteza de medição nos ensaios de resistência elétrica de fios e cabos elétricos para tensões nominais de até 450/750V(Instituto de Tecnologia e Educação Galileo da Amazônia, 2024) CAVALCANTE, Henrique Augusto Mota; ALENCAR, David Barbosa deThe national market for electrical wires and cables faces products of dubious quality, with electrical resistance exceeding normative limits, which may cause fires. This dissertation addresses the importance of ensuring the compliance of these products, focusing on the estimation of measurement uncertainty in electrical resistance tests for wires and cables with nominal voltages up to 450/750V. The "top-down" methodology was applied, using the Ishikawa Diagram, enabling the creation of a mathematical model to calculate combined standard uncertainty. Tests conducted on samples from factories and the market revealed non-conformities, emphasizing the need for improved inspection and measurement processes.Item Smart Gateway 4.0: Prototipagem de dispositivo inteligente para controladoras de fator de potência como estratégia para avanço da maturidade digital através de IoT e Edge Computing em sistemas de gestão de energia(Instituto de Tecnologia e Educação Galileo da Amazônia, 2024) SERRÃO, Alacy da Conceição da Silva; LEITE, Jandecy CabralThe advancement of Industry 4.0 technologies and the demand for energy efficiency require innovative solutions in electric energy management. This dissertation develops the SMART GATEWAY 4.0, an intelligent gateway prototype for power factor controllers, using IoT and Edge Computing. The goal is to optimize the commissioning and management of these controllers and elevate the digital maturity level of industries according to the ACATECH Industry 4.0 Maturity Index.

However, inverter air conditioning systems are a more advanced technology that can offer significant improvements in terms of energy efficiency and reduced environmental impacts. Inverter air conditioning systems use a variable speed compressor, which allows the unit to adjust the compressor speed to meet cooling or heating needs. This means that the compressor does not have to switch on and off continuously, which reduces energy consumption and increases system life. In addition, inverter air conditioning systems are designed to operate more quietly and produce less noise than conventional systems. In Brazil, where demand for air conditioning systems is high, the use of inverter air conditioning systems can have a significant impact on reducing energy consumption and greenhouse gas emissions. In addition, Brazilian authorities have implemented measures to encourage the adoption of energy efficient technologies, including energy efficiency labeling programs to help consumers identify the most efficient appliances. However, it is important to remember that the energy efficiency of an inverter air conditioning system depends on its proper installation and maintenance. It is necessary that the system be sized correctly for the space in which it will be installed and that a regular maintenance program be carried out to ensure that the system is operating efficiently. In summary, the use of inverter air conditioning systems in Brazil can offer significant benefits in terms of energy efficiency and reduced environmental impacts, especially when combined with government incentive measures and proper installation and maintenance practices. It is with these awards that this project will explore the need for technological changes in refrigeration systems, proving their efficiency both in terms of energy and the environment.Item Análise da eficiência energética e impactos ambientais com a nova tecnologia de ar condicionados inverter(Instituto de Tecnologia e Educação Galileo da Amazônia, 2023-09-20) Silva, Wellington José de Castro da; LEITE, Jandecy Cabral; http://lattes.cnpq.br/7279183940171317Air conditioning systems are known for their high energy consumption and the environmental impacts they can cause, especially with regard to greenhouse gas emissions.
