Abstract

La invención se refiere a un dispositivo de protección de circuitos de fase múltiple autoalimentado, que incluye múltiples transformadores de corriente conectados en paralelo entre sí, y asociados con una fase de una carga de fase múltiple para proporcionar señales representativas de la corriente que fluye en una fase asociada. Un conmutador puede activarse para interrumpir la energía a la carga de fase múltiple, y un circuito de determinación de fallos se conecta a los transformadores de circuito y al conmutador, para activar el conmutador ante al menos una condición predeterminada de las señales de corriente. El circuito de determinación de fallos tiene circuitos extensores de pulso digital para convertir las señales de corriente en señales DC, y un temporizador digital para demorar la activación del conmutador.
