This project aims to address preventive maintenance of the busbars in electrical substations via the automatic analysis of thermographic images. To achieve this, the system will use, on the one hand, image processing algorithms for the detection of hot spots and, on the other hand, it will communicate with the SCADA to obtain the control system data in order to characterize the process and subsequently send the analysis results. In addition, the images will be sent to a remote monitoring system, thus creating a historical knowledge base.
