Abstract

Superconducting fault current limiter (SFCL) is an attractive appliance for modern electrical power system. Institute of Electrical Engineering (IEE) at the Chinese Academy of Science (CAS) has successfully demonstrated a three-phase HTS bridge-type fault current limiter (FLC) at a substation in Hunan, China. The FCL suppressed the fault current below 635 A successfully in a 3-phase-to-ground short-circuit field test. Since August 2005, it has been going on a demonstrated long-term reliable operation for one year in the live 110 kV/10.5 kV substation.
