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.

A novel approach for on-line deformation diagnostics of transformer windings
IEEE PES General Meeting, 2010This paper discusses an elegantly simple on-line approach for deformation diagnostics of transformer winding. The Current Deviation Coefficient (CDC) derived from terminal current measurements at a selected high frequency (HF) is found to be an effective indicator for locating deformed section of the winding.

Study on on-line monitoring of windings deformation of power transformer
Eighth IEE International Conference on Developments in Power System Protection, 2004Two kinds of novel on-line monitoring methods, based on measuring primary, secondary currents and voltages to calculate the short-circuit reactance of windings for detecting the windings deformation of power transformer (PT), are proposed in the paper.

Study of transformer winding deformation by frequency response analysis
2013 IEEE Power & Energy Society General Meeting, 2013This paper proposes a methodology to interpret frequency response measurements of a deformed transformer winding due to conductors tilt. To achieve that, geometrical parameters of a three phase prototype transformer is used to simulate the frequency response of one of the windings using the multi-conductor transmission line model.
