| Title: | Calculations of transient eddy current field and dynamic short circuit forces in a large power transformer | Authors: | Ho, SL Li, Y Yang, S Wong, HCC Wong, KF |
Issue Date: | 2006 | Source: | IEEE CEFC 2006 : 12th Biennial IEEE Conference of Electromagnetic Field Computation : April 30-May 3, 2006, Miami, Florida, USA, p. 178 | Abstract: | In this paper, the T-Ω finite element method (FEM) is proposed to study the three dimensional (3D) transient eddy current field and electromagnetic forces acting upon the coils in power transformers. The radial press stress on the coil sections are included in the computation. The axial vibration, displacement and dynamic force of the coil sections are analyzed by modeling the coil as a mass-spring. | Keywords: | Electric coils Electric fields Electric transformers Electromagnetism Short circuit currents Transients |
