Electromagnetic devices such as power transformers and reactors are among the most important pieces of equipment in the power system and are the basis for ensuring the reliability of the power supply. When the power grid is rich in a large number of DC and harmonics, the transformer will have a serious bias magnetic saturation phenomenon, resulting in increased magnetic leakage of the core, increased loss of metal structural parts, increased temperature rise, local overheating, insulation damage, noise increase, vibration intensification, and other consequences. Therefore, how to reduce the loss and temperature rise of the transformer, reduce the vibration and noise under the premise of ensuring the performance of the power transformer, and diagnose the fault of the transformer to ensure the safe and stable operation of the transformer is of great significance.
