Abstract

The method is used in this paper to calculate the leakage magnetic field of SSZ11-50000/110 Power transformer , and by which the structures’ influences to the main leakage flux are analyzed. Through the combination of the product and TEAM Problem 21B, the surface impedance method shows its great advantage in the calculation of eddy current loss.
