Análisis de gases disueltos para monitoreo y diagnóstico de transformadores de fuerza en servicio ;Dissolved gas analysis for monitoring and power transformers in service diagnosis

Abstract

La primera señal de existencia de problemas en transformadores de fuerza es la detección de gases que se generan en el aceite como resultado de los fenómenos térmicos y eléctricos a que están permanentemente sometidos; que degradan el aislamiento y ocasionan fallas incipientes que, si no se detectan a tiempo, pueden devenir en defectos mayores y costosos. El artículo trata sobre el análisis de estos gases, como uno de los métodos más utilizados para el diagnóstico de fallas, en correspondencia con las concentraciones individuales y las relaciones entre esas concentraciones, permitiendo determinar el estado del transformador y reducir los índices de falla. Hace un recorrido completo de los gases generados y de los posibles diagnósticos asociados. Presenta resultados de la aplicación de esta técnica en la Empresa de Construcciones de la Industria Eléctrica (ECIE) Cienfuegos, a partir de las mediciones obtenidas con el medidor portátil Transport X (KELMANLTD).The first sign of the existence of problems in power transformers is the detection of gases generated in oil as a result of thermal and electrical stresses that are permanently subject, which degrade the insulation and cause incipient failures which if not detected in time can become costly and larger faults. The article deals with the analysis of these gases as one of the most used methods for the diagnosis of faults in correspondence with the individual concentrations and the relationships between those concentrations that allow determining the status of the transformer and reduce failure rates. A complete tour of the gases and the possible associated diagnoses with them is done. Presents results of the application of this technique in Building Company of Electrical Industry (BCEI) Cienfuegos, from the measurements obtained with the portable meter Transport X (KELMAN LTD).
