| Abstract: | It's important to investigate the methods about inspecting and diagnosing windings and cores of electrical transformers,in order to avoid the accident and improve the security of transformers by finding the deformation of windings as soon as possible.This paper uses Frequency Response Analysis,by testing and analyzing the vibrating signals via the body,to analyze the loose winding of 220 kVtransformer in Wuwei Substation.New method is proposed for diagnosing whether the winding is loose or not. |
