In transformers,the fault rate of transfomer fault caused by the transformer winding hreakdown is the most.On the baiss of presenting the winding tranform mechanism,the paper explains three winding transform measuring methods of short-circuit impedance method,low-voltage impulse method and frequency response method,and analyzes and compares strong and weak pionts of these methods.
