Abstract

LA INVENCION SE REFIERE A UN DISPOSITIVO PARA LA DETECCION DE CORRIENTE DE DEFECTO CON UNA DISPOSICION DE TRANSFORMADOR DE CORRIENTES SUMAS (1) QUE TIENE LOS DEVANADOS PRIMARIOS (2) PARA UN CIRCUITO DE CORRIENTE A VIGILAR Y UN DEVANADO SECUNDARIO (3). POR LAS CORRIENTES DE DEFECTO CONTINUAS TIENE LUGAR UNA PREMAGNETIZACION DEL TRANSFORMADOR QUE AFECTA NOTABLEMENTE A LA ACTIVACION DEL APARATO DE DETECCION DE CORRIENTE DE DEFECTO PARA CORRIENTES DE DEFECTO ALTERNAS Y CORRIENTES DE DEFECTO CONTINUAS PULSANTES. ESTE DEFECTO SE REMEDIA POR CORTE DE LA LINEA CARACTERISTICA DE MAGNETIZACION, PARA LO CUAL EL DEVANADO SECUNDARIO (3), POR EJEMPLO, SE CARGA CON UNA RESISTENCIA (4).
