With the Brazilian market to international industrial products, it is necessary to check the quality conformity of these products in order to protect the consumer, encouraging continuous quality improvement and promote competition between manufactures [1].The Compact fluorescent lamps (CFL´s or LFC´s) are one of the several products that the National Institute of metrology, quality and technology (INMETRO) regulates the quality. One of the LFC´s testing stages is to keep the LFC´s supplied with electric power for a time period and after this period switch off the LFC´s in according to a predefined schedule. The construction of the LFC´s supplied circuit is done using semiconductors, and these electronics components can cause an undesirable effect (harmonics) in electrical network. These effects cause a variety of problems in driving, conduction and stabilization laboratory circuits. This paper presents an analysis and suggests a solution to the problem of energy quality in one of the laboratories accredited by INMETRO.
Resumo: Existem no mercado brasileiro de equipamentos de iluminação, lâmpadas fluorescentes compactas (LFC) de diversos fabricantes que atendem a normatização específica de qualidade do Programa Brasileiro de Etiquetagem (PBE) que é acompanhada pelo Instituto Nacional de Metrologia, Qualidade e Tecnologia (INMETRO) através dos laboratórios certificadores. Estas lâmpadas são ensaiadas em condições nominais de tensão, o que muitas vezes não retrata a realidade no ponto final de conexão, nas instalações do consumidor. Este artigo apresenta uma avaliação da LFC dentro de condições limites de tensões regulamentadas pelos Procedimentos de Distribuição de Energia Elétrica no Sistema Elétrico Nacional -PRODIST, mostrando o comportamento de 10 amostras de fabricantes diferentes aprovados nos testes de requisitos para aceitação no mercado brasileiro. As lâmpadas foram ensaiadas frente às condições reais encontradas no usuário final, fazendo-se uma comparação dos resultados entre as amostras.
Palavras-Chave: Lâmpadas Fluorescentes Compactas; Qualidade da Energia; Luminotécnica.Abstract: There are in the Brazilian lighting equipment market, compact fluorescent lamps (CFL) from different manufacturers that meet the quality standards according to Brazilian Labeling Program (PBE) which is accompanied by the National Institute of Metrology, Quality and Technology (INMETRO) through the certifying laboratories. These lamps are tested at nominal voltage conditions, which most of time does not demonstrate the reality at the end point of connection, at the user. This paper presents a CFL evaluation front voltage limits conditions regulated by electricity Distribution Procedures in Brazilian Electrical System -PRODIST. The paper demonstrates the behavior of 10 different manufacturers samples approved in standard tests for acceptance in the Brazilian market. The samples were tested against the real conditions found at the end user and the conclusion presents a comparison of the results.
