Abstract
A method is developed for determining the resistance of a high-current system in a furnace, and a model is proposed for a single-phase furnace transformer with a split secondary winding. On that basis, the currents in the transformer and a high-current bus assembly may be simulated in the case of short-circuiting and disconnection of the flexible couplings. The proposed model is verified experimentally. The error in modeling is no more than 10%.
