Abstract
Axial displacement of transformer windings has been studied in this researc h work using a test transformer. The transformer primary winding has 31 dou ble disk coils (approx. 1.3 MVA, 10 kV) and the secondary is a four layer c oncentric winding. A detailed mathematical model was developed for the test object and a comparison was carried out between measured and calculated re sults. It is shown that this model can present the behavior of the transfor mer windings in the frequency domain in case of sound and displaced conditi ons.
