Patent ID: 8914085

Claim:
A superconducting fault current limiter (SCFCL) comprising: a cryogenic tank defining an interior volume; a superconductor disposed in the interior volume; and a voltage detector configured to detect a voltage drop across the superconductor and provide a voltage signal representative of the voltage drop, wherein the superconductor comprises a first superconductor module having a first plurality of superconducting elements electrically coupled in parallel, and a second superconductor module having a second plurality of superconducting elements coupled in parallel, and wherein the first superconductor module and second superconductor module are electrically coupled in series, and wherein the voltage detector is configured to detect a first voltage drop across the first superconductor module and provide a first voltage signal representative of the first voltage drop, and wherein the voltage detector is further configured to detect a second voltage drop across the second superconductor module and provide a second voltage signal representative of the second voltage drop.
