Abstract

The air-core superconducting power transformer has been investigated as one type of superconducting transformer. According to previous investigations, the air-core superconducting power transformer has many advantages compared to an iron-core superconducting or conventional power transformers. However, since these investigations about air-core superconducting power transformers have mainly been done for single-phase transformers, investigations of 3-phase transformers are indispensable as the next step. In this paper, results of previous investigations about single-phase air-core superconducting transformers, such as theoretical characteristics, are expanded into 3-phase. Then, the results of load tests obtained by using an experimental 3-phase air-core superconducting transformer are shown to confirm the results of the theoretical investigations.
