A flat type fault current limiter (FCL) proposed by us consists of a spiral primary winding and high Tc superconducting (HTS) plate. In order to clarify the static current-limiting performance of the flat type FCL, the magnetic field analyses were carried out for small modules of the FCL. The inductance of the FCL was calculated by analyzing the magnetic field. The magnetic field analysis suggested that a high inductance ratio might be realized by radically enlarging both the primary winding and the HTS plate, installing the high permeability material such as an iron on the FCL and stacking the FCL modules vertically in layers. It is also pointed out that the volume of the flat type FCL is smaller than that of the cylinder type FCL with same magnitude of the limiting inductance.
