Abstract

"MONITORAMENTO DE COMUTADOR DE DERIVAÇÃO". A presente invenção proporciona um método e dispositivo para diagnóstico de comutador de derivação de transformadores. A pressão é monitorada em um líquido isolante de um comutador de derivação por um período de tempo em que a comutação do comutador de derivação é realizada. A informação correlacionada à comutação é depois extraída de um diagrama de pressão. O método, preferencialmente usado para comutadores de derivação monofásicos, compreende a etapa de correlacionar quantidades de picos de pressão a centelhamentos específicos da seqüência de comutação. É conseguida uma detecção antecipada de erros, podendo-se, dessa forma, evitar defeitos do transformador. Medições repetidas são seguidas de avaliação de tendências. Se uma tendência indicativa de problemas do comutador de derivação for detectada, um sinal de alarme será disparado. A invenção pode incluir o desligamento do transformador se a pressao exceder um valor de emergência predeterminado, assim como extrair informação da pressão básica no comutador de derivação e converter a mesma ao nível do líquido isolante.
