| Abstract: | After suffering the impact of short-circuit,the damage of power transformer windings should be judged as soon as possible.In this paper,we take a comprehensive analysis on a transformer winding which has suffered the impact of short-circuit by using frequency response analysis(FRA),short-circuit impedance method,winding capacitance test combined with the DGA,winding DC resistance test and voltage transformation ratio test,etc.The comprehensive analysis verified the results with the practical situation |
