Abstract—A power transformer is very important and considered to be the most expensive equipment of the substation. Major problems that may occur to power transformers are found in bushing heat, radiator, on-load tap change and Tank. The reason for this problem is due to a lot of working load and a long operation time of transformers. It will make these points damage and expose to high temperature. If it has been left for a long time, any catastrophe would happen in the future. To detect anomalies and predict possible faults or check the quality of transformers, this paper proposes the development mechanism framework to monitor the temperature variations, and analyze hot regions of transformers using infrared thermograms. This method is economy, convenient and efficient.
Index Terms—Infrared thermogram, power transformer, image processing.
