Abstract

Se describen formas de curvas que se pueden implementar en un protector de transformador que proveen mejor protección contra fallas. Una estructura de clasificación de curva de protector de transformador relaciona curvas de respuesta con el tamaño del transformador y simplifica la selección de curvas de respuesta implementadas dentro de un protector de transformador y el transformador asociado. En un sistema, el protector de transformador es configurado con una curva de respuesta seleccionada con respecto al tamaño de un transformador asociado.
