Abstract

La presente invención se refiere a un sistema de detección de falla a tierra de devanado de generador que incluye una fuente de inyección de señal en comunicación eléctrica con un devanado de un generador de energía eléctrica vía un transformador de inyección. El devanado se puede acoplar a tierra vía una trayectoria a tierra de devanado y la fuente de generación de señal puede generar una señal de inyección capaz de ser inyectada al devanado usando el transformador de inyección. El sistema descrito puede incluir adicionalmente un módulo de protección en comunicación con la fuente de inyección de señal y el generador de energía eléctrica configurado para recibir la señal de inyección y una señal relacionada con la corriente a través de la trayectoria a tierra de devanado, y para determinar la ocurrencia de una condición de falla a tierra de devanado con base al menos en parte en la señal de inyección y la señal relacionada con la corriente a través de la trayectoria a tierra de devanado.
