Abstract

Instalación de protección contra corriente de fallo, con un circuito amplificador (4) para la generación de una tensión de fallo (UA) derivada a partir de una corriente de fallo, con un circuito de comparación (10) para la comparación de la tensión de fallo (UA) con una tensión de referencia (URef), y con un circuito de referencia conectado en una fuente de alimentación (15) para la generación de la tensión de referencia (URef) así como con una tensión de funcionamiento (UB) para el circuito amplificador (4), caracterizada porque están previstos medios (10, 22), que en el caso de caída de la tensión de salida (UN) de la fuente de alimentación (15) por debajo de un valor predeterminado, se eleva la tensión de referencia (URef) al menos a la tensión momentánea de funcionamiento (UB¿) al menos cuando la tensión de fallo (UA) es menor que la tensión de referencia (URef).
