Abstract

Circuito de detección de fuga eléctrica (100, 100A) que comprende: un transformador de corriente (102) de secuencia de fase cero que emite una corriente de fase cero detectando una corriente de fallo a tierra; un condensador (104); y un circuito (108) que funciona cuando dicha corriente de fase cero supera un valor umbral de lado positivo predeterminado o cuando dicha corriente de fase cero disminuye por debajo de un valor umbral de lado negativo predeterminado, y caracterizado porque el circuito controla la carga y descarga de dicho condensador basándose en dicho funcionamiento; puntos (114, 118) de alto potencial; y una primera resistencia (106) prevista entre dichos puntos de alto potencial y dicho condensador (104), en el que dicho circuito (108) emplea una salida de colector abierto y un terminal de salida de dicho circuito está conectado a un contacto (150) previsto entre dicha primera resistencia y dicho condensador (104), y un extremo de dicho condensador (104) está conectado a dicho contacto, y dicho condensador se carga y descarga basándose en la salida de dicho circuito; en el que dicho circuito (108) incluye un amplificador que tiene una salida de colector abierto que funciona cuando dicha corriente de fase cero supera dicho valor umbral de lado positivo predeterminado o cuando dicha corriente de fase cero disminuye por debajo de dicho valor umbral de lado negativo predeterminado, o dicho circuito (108) incluye circuitos OR (110, 112) por cable en los que se aplica un amplificador que tiene una salida en contrafase; y segundas resistencias (128, 130) conectadas entre una salida de dicho amplificador y dicho contacto (150).
