This work presents a distributed-circuit model for analyzing experimental results of fast-ramping behaviors of a saddle-shaped REBCO dipole magnet wound with a bundled conductor. Terminal voltage and center magnetic field were measured during the test performed at 77 K temperature. Our distributed-circuit model accurately reproduced the observed electromagnetic behaviors, demonstrating its validity for the fast-ramping operation of an HTS magnet. We also analyzed the current discrepancy between bundled conductors and Joule dissipation due to the various ranges of contact resistivity.
