Abstract

The model of an inductive current-limiting device consists of a copper coil and a high-T_c superconducting ring which are placed on a ferrite core and are coupled magnetically. The rings were prepared by extrusion of the YBaCuO submicron precursor powder and organic binder, followed by sintering in oxygen atmosphere. The principle of the device's operation is based on a rapid rise of the device's inductance at the transition of the ring from the superconducting to the normal state. The results demonstrate that the device can reduce both the transient and the steady-state fault current significantly. The influence of thermal processes in the ring on the mode of device operation in the circuit is discussed.
