Abstract
En el campo de sistemas de energía eléctrica se proporciona un método para supervisar la operación de una pluralidad de transformadores de corriente dispuestos que se disponen en respectivos grupos de transformadores de corriente (24, 26, 28, 30, 32, 34, 36, 86, 88, 90, 92, 94, 98, 98, 100, 102, 104, 106, 108) dentro de distintas zonas de protección (14, 16, 18, 74, 76, 78) de un sistema de energía eléctrica de múltiples fases (12; 72). El método de supervisar comprende los pasos de: (a) identificar una zona de protección (14, 16, 18, 74, 76, 78) defectuosa dentro del sistema de energía eléctrica (12, 72); (b) identificar un grupo de transformadores de corriente (24, 26, 28, 30,32, 34, 36, 86, 88, 90, 92, 94, 96, 98, 100, 102, 104, 106, 108) defectuosdentro de la zona de protección (14, 16, 18, 74, 76, 78) defectuosa; e (c) identificar una o más fase (A, B, C) defectuosas dentro del grupo de transformadores de corriente (24, 26, 28, 30, 32, 34, 36, 86, 88, 90, 92, 94, 96, 98, 100, 102, 104, 106, 108) defectuoso dentro de la zona de protección (14, 16, 18, 74, 76, 78) defectuosa.
