Fault current limiter providing symmetrical electrostatic shielding
Abstract:
Embodiments of the disclosure include a fault current limiter (FCL) providing symmetrical electrostatic shielding. In some embodiments, a FCL includes a superconductor maintained at a first voltage greater than zero voltage, and an enclosure containing the superconductor, the enclosure maintained at a second voltage greater than zero voltage, wherein the second voltage is different from the first voltage. The FCL may include an electrical connection directly coupling the superconductor and the enclosure, wherein the electrical connection enables each of a plurality of current limiting modules of the superconductor to receive, during a fault condition, an equal or unequal sub-portion of a total voltage drop.
