Monografia Acesso embargado Ensaios para diagnóstico das falhas em transformadores de potência(2017) Pires Junior, José Nilton; Pacheco, Leandro GonçalvesTransformers are extremely important equipment both in the Brazilian electrical system and inside the companies. Failure of this equipment can have serious consequences both in the financial sphere and in the safety of the people who surround it in carrying out the proper maintenance. This work initially presents the necessary theory to capture the perception of the operation of this equipment, simplifying and giving opportunity for a better understanding of the tests that can be practiced for the analysis and diagnosis of transformer faults, highlighting the importance of conventional field tests and a case study, concerning the chromatographic analysis of gases dissolved in insulating oil in a high voltage power transformer, confirming the applicability of the tests proposed herein, where through the analysis performed an internal insulation failure that could have caused the loss of the transformer.
