Abstract

Un método para identificar una condición de falla asociado con un conductor de línea de energía de una red de distribución de energía eléctrica. El método comprende: determinar una corriente de carga transportada por el conductor que está por encima de la corriente de carga mínima, determinado una relación del ángulo de fase aprendida entre la corriente de carga y la señal de origen, determinando la magnitud de la corriente de carga, determinando la relación del ángulo de fase en tiempo real entre la corriente de carga y la señal de origen e indicando una condición de falla cuando la relación del ángulo de fase en tiempo real está dentro del número predeterminado de grados angulares de la relación del ángulo de fase aprendido y cuando la magnitud de corriente de carga exceda una corriente que indique la falla.
