Abstract :
The electromagnetic forces and stresses are calculated while taking into account the axial current component in large power transformers. The 3D electromagnetic field and circuit coupled method based on the A-V-A is employed for studying the 3D transient fields and the corresponding electromagnetic forces acting on the coil. The torsional deflections of low-voltage helical windings are analyzed for the first time.
