| Abstract: | The present of detection and diagnosis technique of transformer winding deformation are summarized,which is usually divided into off-line and on-line testing techniques two categories.The off-line techniques mainly include Low Voltage Impulse method(LVI),Frequency Response Analysis method(FRA) and Short-circuit Reactance method(SCR).Online techniques mainly include Ultrasonic method,Vibration method,the method based on Frequency Response Analysis and the method of Short-circuit Reactance Analysis.The merit and demerit of the methods mentioned above were also compared. |
