Abstract

En el campo de la protección de transformadores de energía se proporciona un método para proteger un transformador de energía que comprende los pasos de: (a) monitorear una señal de indicación de falla externa (12A, 12B, 12C); (b) llevar a cabo una determinación de falla de forma local; (c) llevar a cabo de forma local una determinación de corriente de irrupción; y (d) emitir una señal de viaje final (48) para proteger el transformador de energía si: (i) la señal de indicación de falla externa (12A, 12B, 12C) identifica que una falla ha ocurrido y la determinación de falla llevada a cabo de forma local confirma que una falla ha ocurrido; o (ii) la señal de indicación de falla externa (12A, 12B, 12C) identifica que una falla ha ocurrido y la determinación de falla llevada a cabo de forma local identifica que no ha ocurrido ninguna falla, sino después de un retraso predeterminado la determinación de corriente de irrupción llevada a cabo de forma local confirma la ausencia de una corriente de irrupción.
