Abstract

Las modalidades de la divulgacion se refieren a la deteccion de fallas de giro a giro en uno o mas bobinados de varios objetos; en una implementacion, un detector de fallas recibe un conjunto de mediciones de corriente asociadas con un transformador y utiliza estas mediciones para ejecutar un procedimiento para detectar una falla entre vueltas en el transformador; el procedimiento puede incluir dividir un valor de corriente diferencial de estado estacionario por un valor de voltaje de estado estacionario para obtener uno o mas factores de compensacion, determinar un indicador de amplitud de corriente de magnetizacion multiplicando el valor de voltaje de estado estacionario por uno o mas factores de compensacion, determinar un valor de corriente diferencial compensado combinando el valor de corriente diferencial de estado estacionario con un valor del modificador que incorpora el indicador de amplitud de corriente de magnetizacion, comparar el valor de corriente diferencial compensado con un valor umbral, y declarar una aparición de la falla entre vueltas en el transformador cuando el valor de corriente diferencial compensada excede el valor umbral.
