The internal fault of transformer mainly includes single phase inter-turn short circuit and phase to phase short circuit.Based on Matlab/Simulink, this paper establishes a transformer internal fault simulation model and a differential module with braking characteristics.The simulation results show that the model can effectively simulate the internal fault of a transformer and relay protection.
