Abstract

The inductive type high temperature superconducting fault current limiter (HTS FCL) is one of the forthcoming and progressing applications of HTS, which can make electric power networks more powerful and integrated. In our case a transformer type FCL built up of different types of YBCO and Bi2212 hollow cylinders using a magnetic core with an adjustable air gap was investigated and analyzed with respect to their activation and recovery behaviors. A PC controlled measurement system with electromagnetic relay was developed to record the sudden short-circuit fault processes. For theoretical analysis a new model of the superconductor and 3D FEM program code, to calculate the magnetic field distribution in the HTS and the FCL (which is inserted into the power network) are being developed. This experimental analysis shows the effect of properties of the HTS parts on the operation of the FCL. Having performed the tests, the relevant results allow one to fit the HTS rings to the adequate applications.
