Abstract
Un aparato y método para identificar una falla en devanados de un transformador de distribución mediante el uso de un primer sensor de corriente de bobina Rogowski en una terminal de alta tensión de corriente entrante y un segundo sensor de corriente de una bobina Rogowski conjuntamente en una terminal de baja tensión de corriente saliente y en una terminal de baja tensión de corriente entrante, tal que un primer conductor secundario de la terminal de baja tensión de corriente saliente se pasa en un sentido a través de segundo sensor de corriente de bobina Rogowski, y un segundo conductor secundario de la terminal de baja tensión de corriente entrante para en sentido contrario a través de segundo sensor de corriente de bobina Rogowski; el primer y segundo sensores de corriente de Rogowski generan una señal de salida indicativa de la corriente primaria y una señal de salida indicativa de la corriente secundaria, ambas señales son integradas, generando una señal de la salida proporcional a la corriente primaria y una señal de la salida proporcional a la corriente secundaria así obtener una relación de transformación en operación del transformador de distribución, la cual es comprada con un umbral de relación de trasformación preestablecido para el transformador de distribución y en caso que la relación de transformación en operación exceda este umbral, entonces se envía una señal de falla entre devanados a una unidad de supervisión local o remota.
