Superconducting Fault Current Limiting Transformer (SFCLT) is one of the promising superconducting power apparatus, since it has both functions of superconducting transformer in normal condition and superconducting fault current limiter in fault condition. In this paper, we have designed, fabricated and tested a high temperature SFCLT (HTc-SFCLT) with MCP-Bi2212 bulk coils at liquid nitrogen temperature. The rating of the designed HTc-SFCLT is 3-phase, 6.25 kVA, 275/105V. No-load test and short-circuit test were successfully carried out to verify the fundamental characteristics of HTc-SFCLT as a superconducting transformer. In addition, HTc-SFCLT also exhibited an excellent performance in current limiting test and recovery test at the prospective current of 800 A as a superconducting fault current limiter.
