Abstract: An alert system for a transformer includes a thermographic camera configured to capture thermal images of the transformer, a current sensor configured to generate a sensor signal indicating the current magnitude of a current outputted from the transformer, a storage configured to store a machine learning model, an alert device, and a processing unit configured to obtain image temperature values from the thermal images, obtain magnitude values from the sensor signal, obtain normal temperature values by using the machine learning model and the magnitude values, and instruct the alert device to deliver an alerting signal based on a result of comparison between the image temperature values and the normal temperature values.
