Abstract :
In this paper, a 3-D eddy-current field model for calculating the eddy current losses in an air insulated bus duct system (AIBDS) is proposed. The temperature rises in the AIBDS, including its long linear section and connecting unit, are evaluated using a coupled fluid field and thermal field model. The contact resistance between the copper conductors and the temperature rise in those contact areas are measured and compared with the simulation results in order to validate the proposed methodology
