Abstract

Sistema (2) de detección de funcionamiento en isla para un generador distribuido (DG) dispuesto para conectarse a una red eléctrica, caracterizado porque comprende un primer brazo (10) operativo para conectarse entre la conexión (6) de fase y la conexión (4) de neutro de la red eléctrica; un segundo brazo (12) operativo para conectarse entre la conexión (6) de fase y la conexión (4) de neutro de la red eléctrica, comprendiendo el primer brazo (10) una impedancia mayor que el segundo brazo (12); y un controlador (20) dispuesto para conectar el brazo (10) de mayor impedancia y detectar la corriente a través del mismo, y para conectar el brazo (12) de menor impedancia y detectar la corriente a través del mismo, y para desconectar el generador distribuido (DG) de la red eléctrica en el caso de que la corriente detectada en el brazo (12) de menor impedancia sea similar o igual a la corriente detectada en el brazo (10) de mayor impedancia.
