A Resistive Superconducting Fault-Current Limiter for a Distribution Feeder: Tape Length, Limited Current and Recovery Time

This paper presents a computed design for a fault-current limiter intended for superconducting power devices, with its performance, resource budgets and margins derived from stated assumptions rather than asserted. The headline results are: tape length per phase required at the allowable quench field of 225 m; limited fault current, peak of 2.18 kA; prospective fault current, peak, for comparison of 28.3 kA; ratio of prospective to limited peak current of 13 dimensionless; energy absorbed in the tape during a 100 ms fault after shunt sharing of 196 kJ. Each figure was produced by the deposited computation from the inputs listed in the Methods, and the sensitivity of the conclusions to those inputs is examined in the Discussion. The design is a paper study: it is labelled, on its face and in this abstract, SIMULATED, NOT MEASURED, and no quantity reported here is a measurement of built hardware.
