dc.description.abstractEste trabajo de investigación está enfocado al diagnóstico de los sistemas de aislamiento de los transformadores. Para este propósito, es necesario primero determinar la ley de envejecimiento de activo, el cual está centrado en la identificación de los factores o causas que originan la degradación del transformador. Dentro de este mismo proceso es necesario identificar el efecto sobre el transformador (reducción del nivel de aislamiento, disminución de la capacidad de refrigeración, pérdida de eficiencia, etc.), esto es el modo de falla. Con la comprensión e identificación plena de los factores presentes en el proceso del desarrollo de la falla, es posible medir los parámetros más apropiados para realizar el diagnóstico preciso del sistema del transformador que está presentando la falla, esto permitirá determinar las mejores prácticas en la gestión eficiente del transformador. La tesis propone el desarrollo de métodos de diagnósticos basados en los resultados de ensayos de envejecimiento acelerado realizados a los transformadores en aceite, transformadores tipo seco y transformadores de mediana frecuencia, fundamentado en la teoría de la cinética química. El realizar el estudio sobre diferentes tipos de aislamientos, permite realizar analogías de los procesos de degradación y diagnósticos; igualmente, comparar la ley de envejecimiento de cada tipo de transformador.

dc.description.abstractThis research work is focused on the diagnosis of transformer insulation systems. For this purpose, it is first necessary to determine the asset aging law, which is focused on the identification of the factors or causes that cause deterioration of the transformer. Within this same process, it is necessary to identify the effect on the transformer (reduced insulation level, decreased cooling capacity, loss of efficiency, etc.), that is, the failure mode. With the full understanding and identification of the factors present in the fault development process, it is possible to measure the most appropriate parameters to perform an accurate diagnosis of the transformer system that is presenting the fault, this will allow to determine the best practices in the efficient management of the transformer. The thesis proposes the development of diagnostic methods based on the results of accelerated aging tests carried out on oil-filled transformers, dry-type transformers and medium-frequency transformers, based on the theory of chemical kinetics. Carrying out the study on different types of insulation allows analogies to be made of the degradation and diagnostic processes; similarly, compare the law of aging of each type of transformer.
