A superconducting fault-current limiter
Journal of Applied Physics, 1978A conceptual design is presented for a fault-current limiter for the electrical power utilities which utilizes a superconducting element to commutate the fault current into a shunt resistor. The technical feasibility of the concept is supported by a computer simulation of the switching.

Superconducting fault current limiters
IEE Colloquium on High Tc Superconducting Materials as `Magnets', 1995Fault current limiters (FCLs), superconducting or otherwise, have the potential to reduce fault levels on electricity power networks, and may ultimately lead to lower rated components (i.e. cheaper) being used, or to increased capacity on existing systems.

A practical superconducting fault current limiter
IET Conference Publications, 2009This paper discusses the increasing requirements for an effective means of controlling fault levels on electrical networks and describes the work by Rolls-Royce and partners to develop a practical superconducting fault current limiter. Practical superconducting fault current limiters require materials with a high tolerance to mechanical process ...

Towards the superconducting fault current limiter
IEEE Transactions on Power Delivery, 1991The advent of low-loss AC superconductor wires opens the way to a new current limiting technique: that of extremely fast transition from a superconducting state to a resistive state when the fault current exceeds the conductor's critical current. A 25 kV single-phase prototype is described which consists of a Nb Ti superconducting coil without iron ...

Non‐superconducting fault current limiters
European Transactions on Electrical Power, 2008AbstractThis paper proposes the use of non‐superconducting DC reactor type fault current limiter (NSFCL) instead of superconducting fault current limiters (SFCLs) which has high cost and technology. Proposed FCL consists of three similar sets, each including a diode bridge and a single non‐superconducting DC reactor.

DC superconducting fault current limiter
Superconductor Science and Technology, 2006There is a lack of satisfying solutions for fault currents using conventional technologies, especially in DC networks, where a superconducting fault current limiter could play a very important part. DC networks bring a lot of advantages when compared to traditional AC ones, in particular within the context of the liberalization of the electric market ...

Development of Superconducting Fault Current Limiters
2006 International Conference on Power System Technology, 2006Somewhere in a power utility system, a mishap may cause a short- circuit. The sudden reduction in the power grid's impedance will lead to a surge of current, termed fault current. Sometimes, fault currents can create disasters to power generators, distributors, and consumers.

Cognition on the current-limiting effect of saturated-core superconducting fault current limiter
2015 IEEE Magnetics Conference (INTERMAG), 2015The saturated-core superconducting fault current limiter (SCSFCL) is an important facility for limiting the short-circuit fault current of the power grid. However, the cognition or the judgment on the current-limiting effect, which is the key indicator of the SCSFCL, is not unique.
