Abstract：Based on a great deal of test data in single phase three limb power transformer model, the W-Bm curves related to different DC-biased levels are established in this paper. The 3D transient magnetic field under different DC-biased levels with no-load and load are simulated in MAGNET. The loss and loss density of components in transformer are analyzed. The experimental results are in accordance with the simulation results, confirming the validity of the proposed losses calculation method for transformer under DC-biasing.
