Superconducting fault current limiters

Abstract

Superconducting fault current limiters (FCL) are devices that can enable new and unconventional design of power utility systems. An ideal FCL should have the cabability to intercept and handle a series of faults. At present, FCL technology is not commercialy feasible because of its high cost, except in situations where the fault current cannot be easily reduced by other means. It will become very important as the deregulation environment takes hold and utilities seek more efficient and cost-effective methods to couple grids, improve power quality, and delay expensive upgrades.
