Performance analysis of HTS transformer with fault current limiting properties on short circuit current

The advent of High Temperature Superconductor (HTS) materials has increased interest in research and development of superconducting transformers with major projects being carried out worldwide. Several benefits were accomplished with the introduction such as lower power loss, smaller size and lighter weight transformer. However, recent development on HTS transformer has focused on its ability to also function as Fault Current Limiter (FCL). This paper will show the performance of a non-FCL HTS transformer on short circuit current and predict how it will behave with HTS-FCL transformer winding conductor architectures.
