Abstract

Un dispositivo electrónico inteligente se puede configurar para detectar una onda viajera transitoria causada por una falla eléctrica. Un primer valor de onda viajera de la onda viajera transitoria se puede determinar y un primer tiempo correspondiente asociado con la primer onda viajera se puede determinar. El IED puede recibir un segundo tiempo asociado con un segundo valor de onda viajera de la onda viajera transitoria detectada por un IED remoto. Se puede conocer la distancia al IED remoto. Se puede generar una ubicación estimada en base en la diferencia de tiempo entre el primer tiempo y el segundo tiempo.
