"Diagnostics methods based on comparing two transfer functions are practical instruments for detecting mechanical faults in transformer windings. Movements, displacements and deformations of power transformers windings can be detected on the basis of transfer function change, without opening the transformer tank. The suitable evaluation process for comparing transfer function of power transformers is required. The proposed technique uses Grubbs' test as statistical detector of outliers in a univariate data set. The CHIRP signal method seems to be suitable tool for an acquisition transfer function of transformers because it is possible to get more characteristics in a short time. The integration of CHIRP signal method and Grubbs' test would create a powerful system for detection of winding faults."@en . . . "neuvedeno" . .
