To monitor the operating conditions of power transformers in real-time and predict the loosening faults of the transformers, the finite element simulation software is used to model the transformer, to simulate the vibration of the transformer core under different compressive stresses during its operation, and to analyze the vibration signal in this paper. Firstly, the transformer is modeled, and the electromagnetic field distribution of the transformer is solved through field-circuit coupling. Then, the force condition and vibration displacement distribution of the transformer are solved throu...
