Abstract
1.- Aparato para detectar una discontinuidad o una irregularidad en una línea o neutra de retorno de una red de distribución de energía eléctrica que incluye a la línea neutra de retorno, una línea activa y un retorno a tierra, donde el aparato incluye: medios para medir un cambio de voltaje asociado con una conmutación deliberada de una impedancia conocida en la red eléctrica, donde este cambio de voltaje se debe a una discontinuidad o irregularidad en la impedancia en la línea neutra de retorno; medios para implementar un algoritmo para identificar la discontinuidad o la irregularidad en la impedancia en presencia de variaciones permisibles en el voltaje nominal del suministro a la red eléctrica, incluyendo los cambios de voltaje que resultan de operaciones de la red que limitan u ocultan una discontinuidad o una irregularidad en la impedancia en la línea neutra de retorno; y medios para comparar un resultado de esa medición con una referencia, para proporcionar una indicación de la discontinuidad o la irregularidad en la impedancia.
