摘要：
Based on the exPressions of transient three phase short circuit current, the formulas of radial and axial electromagnetic forces acting on the transformer windings are derived. The short circuit forces include three components: d-c component, fundamental frequency component and double frequency component. Using a 17000 KVA transformer as a model, the 2D leakage magnetic fields and s-c forces with different phase angle are calculated by FE method. The results are compared with design formulas and some conclusions are obtained. © 1990, IEEE. All rights reserved.
