Abstract

The air-core superconducting transformer, which has a large magnetizing current, has been proposed as a power transformer that has the function of a shunt reactor. In this paper, the basic design procedure for the air-core superconducting transformer is presented. By using this procedure, a 500/√(3 kV)-66/√(3 kV)-300 MVA single phase air-core transformer is designed for a model cable transmission system. Then, the performance of this transformer in the model cable transmission system is analyzed, and it is confirmed that the air-core superconducting transformer can function as a shunt reactor in addition to the principal function as a power transformer
