Mechanical Fault Types Detection in Transformer Windings Using ‎Interpretation of Frequency Responses via Multilayer Perceptron

R. Behkam; A. Moradzadeh; H. Karami; M.S. Nadery; B. Mohammadi ivatloo; G.B. Gharehpetian; S. Tenbohlen

Volume 11, Issue 1 , April 2023, , Pages 11-21


  The Frequency Response Analysis (FRA) technique has advantages in identifying faults related to power transformers, but it suffers from the interpretation of frequency responses. This paper presents an approach based on statistical indices and Artificial Neural Network (ANN) methods to interpret frequency ...  Read More

Characterization of Power Transformer Electromagnetic Forces Affected by Winding Faults

V. Behjat; A. Shams; V. Tamjidi

Volume 6, Issue 1 , June 2018, , Pages 40-49


  Electromagnetic forces in power transformer windings are produced by interaction between the leakage fluxes and current passing them. Since the leakage flux distribution along the windings height is in two axial and radial directions, so the electromagnetic forces have two components, radial and axial. ...  Read More
