Using of high temperature superconductive in secondary winding of two types of transformers: Fault current limiter and current injection transformer

The Types of applications in which superconductivity has the potential to be effective in an electric power system can be separated into two general classes. The first type includes those technologies in which superconductivity is simply a replacement of existing resistive materials, for example, cable, motor, generators, and transformer. The second type includes technologies that will be enabled by superconductivity and that have little or, at most, limited capability if conventional resistive or other materials are used. Examples are superconducting magnetic energy storage (SMES) and large fault current limiter (FCL) [1].
