Abstract

Un dispositivo electrónico inteligente puede proporcionar una protección contra fallos de conexión a tierra a componentes de un sistema de suministro de energía eléctrica usando un comparador de amplitud y un comparador de ángulo de fase, configurados para detectar fallos de manera independiente. El IED puede incluir una lógica de selección configurada para seleccionar la salida de uno del comparador de ángulo de fase y el comparador de amplitud, con la exclusión del otro, en base a las condiciones del sistema. En consecuencia, cuando las condiciones del sistema son tales que un comparador de ángulo de fase es más adecuado para detectar un fallo, la lógica de selección puede seleccionar la salida del comparador de ángulo de fase. Del mismo modo, cuando las condiciones del sistema son tales que un comparador de amplitud puede detectar mejor un fallo, la lógica de selección puede seleccionar la salida del comparador de amplitud. Un sistema de protección también puede incluir un detector de fallos en la zona configurado para detectar fallos en la zona.
