Abstract: The transient eddy current fields are short-circuit forces upon the coils of large power transformers are analyzed. The proposed approach is based on the A-V-A formulation in which the eddy current field and the electric circuit equations are solved simultaneously. The effectiveness of a magnetic bypass plate near the coils ends for reducing the eddy current loss and the local over-heating is discussed. A simulation to study the transient short-circuit behavior of a 720-MVA power transformer using the proposed coupled approach is reported.
