Abstract :
Fault 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. The electricity industry is, therefore, very interested in such devices providing that they satisfy the relevant economic as well as technical constraints. This paper discusses the general operation of a FCL as a circuit element and, more specifically, the operation of superconducting FCLs. A project, led by EA Technology, to develop a prototype 11 kV superconducting fault current limiter, is also discussed
