Investigations of HV and EHV superconducting fault current limiters

In close cooperation, GEC Alsthom, Alcatel Alsthom Recherche and Electricite De France are investigating the technical feasibility and the economical impact of low T/sub c/ superconducting fault current limiters, intended for the French HV and EHV electrical grids. The program includes the complete design of a 63 kV/1.25 kA/5 kA/spl circ/ version, experienced on current and voltage models. Extensions to the HV prototype demonstration, and to the EHV fault current limiters, are also discussed in this paper.<
