Abstract

La condicion de fase abierta de un transformador de potencia en reserva se detecta mediante la monitorizacion de funciones de las corrientes de fase; las funciones tienen parámetros calculados con base en corrientes de referencia, que constituyen una "huella dactilar" cuando todas las fases estan conectadas.
