Quick response excitation type superconducting generators which are recently being developed have suprerconductors in the magnetic field windings. In those generators, the current of the magnetic field have to be controlled by extremely high speed. Therefore, high speed surge voltages are applied to the superconducting magnetic field windings. Surge characteristics for the transformers of normal temperature are well studied and reported up until now, but we can hardly find out the reports about the superconducting field windings. Consequently we are unable to apply the research results of the normal temperature conductors to the superconducting magnets by various reasons. This report shows the analysis, theoretical considerations and the results of experiments of the voltage distribution when the high speed surge voltages are applied to the superconducting magnet.
