Abstract

Un montaje de proteccion contra fallas por arco electrico y un metodo correspondiente determinan si se encuentra presente un arco electrico en circuitos electricos. El montaje suministra energia electrica rapidamente sin disipar calor excesivo, mientras se suministra energia electrica al montaje. El montaje comprende un sensor, un circuito de ruido de banda ancha, un controlador, y una fuente de suministro de energia electrica de doble modo. El sensor detecta una corriente que fluye en el circuito electrico y desarrolla una senal correspondiente del sensor. El circuito de ruido de banda ancha determina la presencia de ruido de banda ancha en la senal del sensor y produce una senal de salida correspondiente. El controlador procesa la senal del sensor y la senal de salida, en una forma predeterminada, para determinar si se encuentra presente una falla por arco electrico en el circuito. La fuente de suministro de energia electrica de doble modo suministra energia electrica al sensor, al circuito de ruido de banda ancha y al controlador, usando un primer modo y conmutando posteriormente a un segundo modo. El primer modo alcanza un estado estacionario mas rapido que el segundo modo. La figura mas representativa de la invencion es la numero 1.
