Abstract
This paper investigates the leakage flux and the iron loss generated in the laminated silicon sheets of the core or the magnetic shields of large power transformers. A verification model is well established, and proposed parabolic model (non-saturated region) and hybrid model (saturation region) to simulate the magnetic properties of the silicon steel with different angles to the rolling direction. An efficient analysis method is implemented and validated. The calculated and measured results with respect to the test models are in good agreement.
