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.

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.

Of course, there are other themes for competitiveness to be obtained in all fields, however, the focus on the ESG issue (English acronym for Environmental, Social and Governance) is another indication of how much the theme “sustainability” has gained more and more relevance in the market and consequently in business. In fact, the environmental issue was cited as one of the main points of concern for today's society in the most recent edition of The Global Risks Report, by the World Economic Forum (WEF), which highlighted issues such as extreme weather events, failures in negotiations regarding climate, environmental damage and loss of biodiversity as major threats. In addition to the environmental aspect, society has also shown itself to be increasingly concerned with social and governance values. Socially, it has become essential to ensure a diverse corporate environment. More transparency and honesty in business began to be valued. Thus, the three pillars of competitiveness are basically centered on: Within the context discussed above, this work deals specifically with the ISO 50001 Standard - Energy Management System, where a process is described that aims to scientifically record and analyze the events that occur during the processes of monitoring energy consumption by electrical equipment. significant energy use (USE) as part of the standard certification process. During the process, all the tools applied to develop the work were used, such as; Strategic Planning, PDCA, Swot Matrix, o and Hoshin Plan. The need is detailed in the organizational strategic planning and continues to be deployed in the organization. As a final result, the objective is to obtain certification in the standard with the understanding and fulfillment of all the items in question, within the planned period. This case study that portrays the certification process of an electronics company in the Energy Efficiency Management System standard is of fundamental importance for bringing results to the organization in terms of reducing energy consumption and reducing impact on the environment and improvements arising. The methodology used in the company was based on the energy diagnosis of the organization and using the PDCA method. The objective of the article is also to demonstrate, at the end, the level of knowledge of employees for the development that involves Energy Management after the organization's certification, done through field research.Item Metodologia para modelamento de usina fotovoltaica com aplicação do software retscreen(Instituto de Tecnologia e Educação Galileo da Amazônia, 2022-11-01) JAMEL, Fábio Castro; NASCIMENTO, Manoel Henrique Reis; http://lattes.cnpq.br/0850846128967798In the actually World, searching for new energy Technologies in increasing, and being far from large metropolitan centers is an aggravating factor for the socioeconomic developmet of municipalities.
