Abstract
The axial and radial displacement of transformer windings can lead to significant defects,
accounting for a large proportion of transformer failures. These defects not only result
in power outages but also pose serious safety
risks. This paper presents a novel methodology for the localization of axial and radial
displacement in air-core transformers. Utilizing Frequency Response Analysis (FRA) coupled with deterministic algorithms. The proposed approach involves analytical modelling
of the transformer, data collection through software simulation, and measurements. By creating a comprehensive lookup table for potential winding displacements, this method leverages software simulations in Python and SPICE
to accurately predict and identify the location
winding deformations. The deterministic algorithm is implemented as a key factor in the reliable prediction of such displacements.
