Abstract

APARELHO E MÉTODO PARA IDENTIFICAR UMA FALHA NOS ENROLAMENTOS DE UM TRANSFORMADOR DE DISTRIBUIÇÃO. Um aparelho e método para identificar uma falha nos enrolamentos do transformador de distribuição usando um primeiro sensor de corrente de bobina de Rogowski em um terminal de alta tensão de corrente de entrada e um segundo sensor de corrente de bobina de Rogowski em conjunto com um terminal de baixa tensão de corrente de saída e em um terminal de baixa tensão de corrente de entrada, de modo que um primeiro condutor secundário do terminal de baixa tensão de corrente de saída seja passado em uma direção através segundo sensor de corrente da bobina de Rogowski e um segundo condutor secundário do terminal de baixa tensão da corrente de entrada seja passado na direção oposta através do segundo sensor de corrente da bobina de Rogowski; o primeiro e o segundo sensores de corrente da bobina de Rogowski geram um sinal de saída indicativo da corrente primária e um sinal de saída indicativo da corrente secundária, ambos os sinais são integrados, gerando um sinal de saída proporcional à corrente primária e um sinal de saída proporcional à corrente secundária para obter uma relação de transformação em operação do transformador de distribuição, que é comparada com uma espira pré-definida limite de relação para o transformador de distribuição e caso a relação de giro em operação ultrapasse este limite, então um sinal de falha entre enrolamentos é enviado para um unidade de supervisão local ou remota.
