Zusammenfassung: | To ensure reliable operation of Power transformer, condition monitoring of transformer becomes obligatory. In this paper, condition assessment of transformer oil under various working conditions is performed using UV-visible spectrophotometer. Test samples include both laboratorial prepared ones and those obtained from in service transformers. An index table of spectral responses for various faults which predominantly occur in the transformer is developed. The index table will acts as a reference for spectral response of faulted transformer oil. In this paper, an attempt has been made to determine the quality of transformer oil using their spectral response characteristics. Keywords: transformer, dielectrics, oil transformer, spectral response, UV spectra. Para assegurar uma operacao confiavel do Poder transformador, monitoramento de condicao de transformador se torna obrigatoria. Neste trabalho, avaliacao do estado do oleo do transformador sob varias condicoes de trabalho e realizado usando espectrofotometro UV-visivel. As amostras de teste incluem tanto laboratoriais entes preparados e aqueles obtidos a partir de transformadores em servico. Uma tabela de indice de respostas espectrais para varias falhas que ocorrem predominantemente no transformador e desenvolvido. A tabela indice funciona como uma referencia para a resposta espectral do oleo do transformador com defeito. Neste trabalho uma tentativa foi feita para determinar a qualidade de oleo de transformador com as suas caracteristicas de resposta espectral. Palavras-chave: transformador, dielectrics, transformador de oleo, a resposta espectral, espectros UV. |
