Abstract
Las modalidades de la descripción se relacionan con sistemas y métodos para monitorear y diagnosticar la salud del transformador; en una modalidad, se puede proporcionar un sistema que incorpora un aparato de diagnóstico para monitorear un transformador de potencia; varios elementos de detección de corriente eléctrica y un aparato de análisis de gas disuelto (DGA) se acoplan al transformador y al aparato de diagnóstico; el aparato de diagnóstico se puede configurar para detectar una falla transversal en el transformador al ejecutar un análisis de flujo de corriente eléctrica con base por lo menos en parte en los valores de corriente eléctrica recibidos de los elementos de detección de corriente eléctrica; el análisis de flujo de corriente eléctrica implica comparar una relación del valor de corriente eléctrica diferencial y un valor de corriente eléctrica de restricción con un valor umbral; el aparato de diagnóstico también puede utilizar datos del DGA proporcionados por el aparato de DGA para detectar una condición anormal relacionada con el gas en el transformador; una señal relacionada con la salud del transformador y/o una señal de control que se basa en los datos de la salud del transformador, puede ser transmitida por el aparato de diagnóstico.
