Research on Transformer Winding Deformation and Winding Resistance
DEStech Transactions on Environment, Energy and Earth Science, 2016 In this paper, the influence of transformer winding deformation on the equivalent electrical parameters is studied, and the proximity effect and skin effect caused by AC current in the wire are simulated. It is verified that the current distribution will be affected by the proximity effect and skin effect.

MACHINE-TRANSFORMER UNITS FOR WIND TURBINES
Electrical Engineering & Electromechanics, 2016 Background. Electric generators of wind turbines must meet the following requirements: they must be multi-pole; to have a minimum size and weight; to be non-contact, but controlled; to ensure the maximum possible output voltage when working on the power supply system. Multipole and contactless are relatively simply realized in the synchronous generator

High frequency model of transformer winding
Electrical Engineering in Japan, 2003 AbstractA high frequency model of transformer winding is used to analyze the voltage oscillations due to various excitations such as the very fast transient overvoltage which occurs at the time of disconnecting switch operations. Usually, a circuit of interlinked inductances and capacitances is used for this purpose, in which circuit parameters have to
