Estudio y análisis de fallas térmicas, dieléctricas y mecánicas en transformadores monofásicos en la empresa eléctrica CNEL Guayas-Guayaquil.

Abstract

The objective of this project was the study and theoretical-practical analysis of single-phase transformers in relation to power failures that occurred during their operation, whose importance and understanding of the results of the dissolved gas analysis (DGA) allowed to know the evaluation of its operation, through electrical measurements to prevent interruptions, due to the common failures observed in electrical transformers in their structural system, maintenance and mode of operation. contributed to shorten the useful life of these. This degree proposal sought to demonstrate through the theoretical study, the optimal capacity of the transformers based on the load profile, the associated losses and the initial cost of the equipment. Your changes in your regulations in order to improve the efficiency levels of the distribution transformers installed in your electrical system. Also, the technical reports of the National Electricity Corporation CNEL EP were analyzed, in order to know the tests that were carried out on the transformers that are in operation in the Ecuadorian electrical network, and based on this analysis and the results obtained, propose an operation and maintenance strategy for transformers based on compliance with ASTM D 877A-02 STANDARD. This investigation also had the preventions to avoid failures in electrical transformers, with examples, showing that these could be avoided through a continuous review of the health condition of the Transformer through an effective analysis by DGA in combination with an effective evaluation of the condition.
