Abstract

Un conjuunto de mediciones de corriente se puede transmitir desde un dispositivo electrónico inteligente (IED) remoto a un IED local. Las mediciones de corriente pueden comprender una marca de tiempo y/o pueden estar asociadas con información de marca de tiempo para permitir que el IED local alinee en tiempo la medición de corriente local con la medición de corriente remota. El IED local puede detectar una falla dentro del segmento del sistema de energía definida por los IED local y remoto al comparar una corriente de operación con una corriente aumentada limitante. También se puede detectar una falla al comparar la corriente de operación con una corriente nominal aumentada Las corrientes de operación y limitantes se pueden derivar de las mediciones de corriente local y remota. El aumento de corriente limitante se puede derivar a partir de las características de IED local y/o remoto. Las mediciones de corriente pueden corresponder con un componente de secuencia negativo y/o un componente de secuencia cero de un conjunto de medición de corriente trifásico.
