Abstract
Abstract The 1 MVA resistive type single phase AC fault current limiter (FCL) was build and successfully tested by capacitors battery discharge. FCL rated voltage is 3.5 kV, current 250 Arms. The 240 m of HTS tape (type SF12100 by SupePower) was used for FCL production. The FCL consists of 8 bifilar coils each wound onto glass-fiber 70 mm diameter tube and connected in series. The HTS tapes were additionally stabilized with Cu laminated highly resistive foil. During the tests of separate FCL coils at 380 V an excellent limiting performance was observed. Tested FCL coil was switched off after 75 ms, the maximum temperature at the HTS tape was less then 230 K, the recovery time was about 5 s.
