| Abstract |
The fault current limiting characteristics of a flux-lock type superconducting fault current limiter (SFCL) considering hysteresis characteristics of a flux-lock reactor, which is an essential component of the flux-lock type SFCL, were investigated. In the normal state, the hysteresis loss of iron core in the flux-lock type SFCL does not happen due to its winding"s structure. From the equivalent circuit for the flux-lock type SFCL and the fault current limiting experiments, the hysteresis curves could be drawn. Through the hysteresis curves together with the fault current level due to the inductance ratio between the primary and the secondary windings, the increase of the number of turns in the secondary winding of the flux-lock type SFCL made the fault current level increase. On the other hand, the saturation of iron core was prevented. |
