Abstract

Las modalidades de la descripcion se relacionan con la deteccion de fallas entre vueltas en uno o mas devanados de varios objetos; en una implementacion, un detector de fallas utiliza un algoritmo de proteccion diferencial para detectar una falla entre vueltas en un devanado de un reactor de derivacion de tres fases; se usan varias mediciones de voltaje y corriente llevadas a cabo en el reactor de derivacion de tres fases para calcular un valor de diferencia entre un parametro basado en voltaje y un parametro basado en corriente; el parametro basado en voltaje es indicativo de un desequilibrio de voltaje negativo normalizado y el parametro basado en corriente es indicativo de un desequilibrio de corriente negativo normalizado; se declara una falla de devanado entre vueltas cuando el valor de diferencia no es igual a cero.
