Bi2223 bulk
flux flow resistance
inrush current
voltage-current density characteristics
We have proposed a current limiting element using the flux flow resistance in a high temperature superconductor (HTS) for a pulse over-current such as a magnetizing inrush current in a transformer. We experimentally investigated the generation process of flux flow resistance in a Bi2223 bulk with an inrush current. The voltage-current density characteristics and their dependence on the joule heat generated in the Bi2223 bulk were measured. Comparing the results with the characteristics for the ac over-current, we made it clear that the both have almost the same characteristics.
