Abstract

DISPOSICION DE CIRCUITO PARA RECONOCIMIENTO DE UNA CORRIENTE QUE PASA POR UNA LINEA ELECTRICA. COMPRENDE UN CIRCUITO DE ACOPLAMIENTO (K) CON DOS COMPARADORES (1, 2), CONECTADO A UNA RESISTENCIA OHMIA (R) INTERCALADA EN LA LINEA. DE LOS DOS COMPARADORES (1, 2) EL QUE CORRESPONDA EN FUNCION DEL SENTIDO EN QUE LA CORRIENTE PASA POR LA LINEA, RESPONDE TAN PRONTO COMO LA CORRIENTE CIRCULANTE POR LA LINEA ALCANZA UN VALOR UMBRAL PREDETERMINADO. LAS SALIDAS DE LOS COMPARADORES (1, 2) ESTAN UNIDAS CON UN CIRCUITO DE ELVALUACION (A) PARA SEÑALES DIGITALES, SEARADO GALVANICAMENTE DEL CIRCUITO DE ACOPLAMIENTO (K), Y ESTAN ALIMENTADOS POR UNA FUENTE DE TENSION (5) SEPARADA GALVANICAMENTE DEL CIRCUITO DE ACOPLAMIENTO (K), Y ESTAN ALIMENTADOS POR UNA FUENTE DE TENSION (5) SEPARADA GALVANICAMENTE DEL CIRCUITO DE ACOPLAMIENTO (K). PARA EXCLUIR LA POSIBILIDAD DE QUE EL CIRCUITO EVALUADOR (A) INFLUYA SOBRE EL RECONOCIMIENTO DE LA CORRIENTE, LAS SALIDAS DE LOS COMPARADORES (1, 2) ESTAN CONECTADAS A, COMO MINIMO, UN OPTACOPLADOR (8), CUYO LADO RECEPTOR ESTA UNIDO CON EL CIRCUITO EVALUADOR (A).
