An on-line monitoring method for winding deformation of power transformers
2013 IEEE 8th Conference on Industrial Electronics and Applications (ICIEA), 2013A novel method for on-line monitoring winding deformation of transformers is proposed. Short-circuit reactance (SCR) of transformers in service is calculated through online measurement of the voltage and current at primary side and secondary side with different loads, which could reflect the deformation of transformer windings.

Transformer winding deformation detection analysis and typical cases
2016 IEEE International Conference on High Voltage Engineering and Application (ICHVE), 2016The transformer is subjected to the outlet and near area short circuit impact or the transportation in the collision, the winding may appear the distortion. After the winding deformation, the transformer winding may be local insulation failure, in the operation of the formation of partial discharge, under the action of lightning and other over-voltage,

Diagnostics of Transformer Windings Deformation Based on Transfer Function
2014The deformation of transformer windings after a short circuit was analyzed by studying the criterion for the transfer function. First, the lumped parameter method was used to establish the equivalent circuit of transformer winding, the losses, and mutual inductance was added in it.

The transfer function method is a reliable tool for the detection of the transformer winding deformation and displacement, but determining the extent of winding deformation without considering its location results in unreliable estimations. In addition, there is no exact method for detecting the location of deformation in the transformer windings. This
