Patent ID: 6900718

Claim:
A resistive superconducting current limiter comprising two straight conductor track sections each having a conductor track width b and a transverse first conductor cross section Q 1 which carries current when limiting occurs; and a corner element arranged between the two straight conductor track sections; wherein the corner element includes a circular ring section having the width b and a radial second conductor cross section Q 2 which carries current when limiting occurs; wherein each of the two straight conductor track sections and the corner element includes a layer of high-temperature superconductor and an electrical bypass; wherein the radial second conductor cross section Q 2 is different in geometry and/or conductivity from the first conductor cross section Q 1 . wherein, in the circular ring section, the superconducting layer is unchanged from the straight conductor track sections; wherein a centroid, with average conductivity, of the second conductor cross section Q 2 is locally closer to an outer radius than to an inner radius of the circular ring section; and wherein the bypass is thinner along the inner radius than along the outer radius of the circular ring section.
