In this paper the electric arc fault in the high voltage winding turn of the power autotransformer has been investigated. 3D magnetic field distributions in the leakage domain and electrodynamic forces acting on high voltage winding have been calculated. Finite Element Method was used for the magnetic flux density simulation. The elctrodynamic force value under the fault exceed significantly the nominal mechanical stresses of the winding.
