By analyzing the transient short-circuit current and leakage magnetic field in a transformer, it is proposed that the axial short-circuit electric force is a dynamic one. In order to give the force effect on the windings, clamps and pressboards, a mass-spring vibrating system is used as a model for study. The theoretical analysis is verified by simulation using MATLAB. Preventive measures are proposed based on the discussion of reasons for the axial instability in transformers.
