The development momentum of the power industry is pushed by the increasing demands and continuous progress in all sections of the economy. The improvement of the voltage grade of transmission lines is imminent, and the capacity of a single transformer continuously increases, thereby resulting in the serious problem of magnetic leakage, which that can aggravate the stray loss of transformers and the degree of winding deformation. The simulation model of leakage inductance under the different fault states of transformer winding was proposed on the basis of finite element method to reduce the threat to the safe and stable operation of power grids caused by the winding insulation damage from magnetic leakage. ANSOFT software was used to establish the physical model of 800 kVA and 10 kV true distribution transformers, and the leakage inductance values of transformer winding with a three-phase grounding short circuit, a turn-to-turn fault, and an inter-turn fault were analyzed. Finally, the accuracy of the model was verified through the finite element simulation. Results indicate that the leakage inductance of transformer increases by 30% in a three-phase short circuit, the leakage inductance is negatively correlated with the number of fault turns in a turn-to-turn fault, and the leakage inductance has a nonlinear positive correlation with the number of fault turns in an inter-turn fault. The proposed method provides references for the detection and evaluation of transformer operation fault.
