<p>An inductive Superconductive Fault-Current Limiter (SCFCL) comprising an iron core (3) having a wound primary winding (1) and a short-circuited superconductive secondary (2). The secondary remains superconductive up to a fault current level in the primary, after which the SC secondary becomes resistive, the primary amp. turns are not balanced and the device becomes highly inductive so limiting the fault current. The invention provides a means of increasing the fault current threshold without exceeding available critical SC current density levels and with a moderate SC coating thickness by using a stack of SC coated washers having a large radial extent compared to the coating thickness. <IMAGE></p> |
