Análisis dinámico para el diagnóstico de transformadores de potencia basada en su condición

Abstract

The article discusses the strategic approach to power transformer maintenance, focused on their condition. This technique seeks to establish a base of electrical and dielectric variables to foresee failures and take precautions. Tests, both in the laboratory (FAT) and in the field (SAT), are essential to acquire and store historical data since the first maintenance of the equipment. A detailed analysis of these variables is performed according to IEEE standards, evaluating trends and slopes to predict failures and suggest preventive corrections. In the electrical sector, power transformers are vital, so constant monitoring is required. Methods have been developed for diagnostics and decision making to avoid unscheduled downtime of this equipment, which leads to high costs. In summary, the article details a comprehensive approach to power transformer maintenance, highlighting the importance of detailed analysis of electrical and dielectric variables, continuous monitoring, and condition-based preventive actions to maintain functionality and reduce costs associated with downtime.
