Abstract

Un método, un dispositivo y un sistema para detectar una falla para un dispositivo protector. El dispositivo puede recibir una señal de entrada y detecta un pico de energía en la señal de entrada. Si se detecta un pico de energía en la señal de entrada, el dispositivo simultáneamente deshabilita el mecanismo de disparo para uno o más dispositivos protectores e inicia un periodo de tiempo. Durante el remanente del periodo de tiempo, el dispositivo compara la señal de entrada y el valor de umbral. Si, durante el remanente del periodo de tiempo, la señal de entrada excede el valor umbral, y si la falla se origina dentro de una región entre los múltiples dispositivos sensores, entonces el mecanismo de disparo para cada dispositivo protector es habilitado de nuevo.
