O diagnóstico de falhas incipientes em transformadores está diretamente relacionado à avaliação das condições do sistema de isolamento. Este estudo aborda a relação entre os gases dissolvidos no óleo e a qualidade do óleo mineral isolante utilizado em transformadores de potência. As Redes Neurais Artificiais são utilizadas na abordagem da avaliação das condições operacionais do óleo isolante e do sistema de isolamento de um transformador utilizando os dados das análises físico-químicas e cromatográficas (Análise de Gás Dissolvido). Este livro propõe um método que pode ser usado para extrair informações cromatográficas usando as análises físico-químicas através de Redes Neurais Artificiais. As análises atuais das propriedades físico-químicas fornecem apenas diagnóstico do estado do óleo, o que não permite o diagnóstico de falhas incipientes. Acredita-se que as concessionárias de energia podem melhorar a confiabilidade na previsão de falhas incipientes a um custo menor com este método, uma vez que apenas um ensaio é necessário. Os resultados mostraram que esta estratégia é promissora.
