摘要
One of the programs in the Ministry of Economy and Trade and Industry (METI) project regarding R & D YBCO conductor is to evaluate the applicability of the developed conductor toward several applications. This paper focuses on a fault Current limiter (FCL) as one of the expected power applications. YBCO tape conductors with ion beam assisted deposition (IBAD) substrate are used in this work. in order to obtain high resistance of the conductor, which is preferable to an FCL, the thickness of the protecting layer made of silver was decreased as possible. Then high-resistive metal stabilizing layer is attached on the silver layer to improve stability. Obtaining the relevant Current limiting performance on short sample experiments, model coils were developed to aim the 6.6 kV-class FCL. Short circuit experiments were implemented with a short circuit generator. The coil successfully restricted the short circuit current over 17 kA to about 700 A by the applied voltage of 3.8 kV. which is nominal phase-to-ground voltage. The experimental results show good agreement with computer analyses and show promising toward the application. (C) 2008 Elsevier B.V. All rights reserved.
