Estimativa da incerteza de medição nos ensaios de resistência elétrica de fios e cabos elétricos para tensões nominais de até 450/750V. 2024. 70p. Dissertação (Mestrado em Engenharia, Gestão de Processos, Sistemas e Ambiental) – Instituto de Tecnologia e Educação Galileo da Amazônia, Manaus, 2024.https://rigalileo.itegam.org.br/handle/123456789/198The 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.pdf.Incerteza de MediçãoResistência ElétricaConformidade de ProdutosFios e Cabos ElétricosSegurança ElétricaDissertação3.04.00.00-7 Engenharia Elétrica
