Abstract :
The authors studied experimentally the problem of the in-rush current of a superconducting transformer using a small experimental model system with a Bi-2223 HTS winding. The in-rush current with a ceiling current of more than 10 pu was applied. The experimental result shows the remaining of a finite resistive voltage even for a primary current smaller than its DC critical value after the decaying of the initial in-rush over current
