Resumen
In the present work an analysis is carried out on the predictive maintenance using the thermographic technique in the feeder "Guanujo Centro" and its distribution transformers of the Electric Company CNEL EP Bolivar in order to detect possible anomalies and propose the respective solutions.
For the realization of this work some factors of great importance are considered, taking as reference, a reading frame of the SCADA system of the month of March 2018, after that the load curve is analyzed in its maximum demand of this feeder.
With this background, a visual inspection is carried out, then a complete study of the feeder using thermography through which hot spots are detected in badly adjusted elements, corrosion, high chargeability in transformers, environmental contamination (in the elements that are part of an electrical system), point of disconnectors and in aerial bridges of connections in medium and low voltage.
Once this work is done, it is determined that it is necessary to carry out a complete study in all the substations and feeders that are part of the CNEL EP Bolívar electrical system, in order to solve all the anomalies found in order to provide solutions to improve the electric service in a coordinated, planned way and reduce the quality index.
Finally, some conclusions and recommendations are expressed in a general manner, which emphasizes the results obtained from the technical staff that carries out this work and serves for future research on predictive maintenance issues in order to improve reliability, optimize resources and specialize in technical staff that does it.
