High Temperature Superconducting Transformer

High temperature superconducting (HTS) transformers offer many benefits over conventional power transformers for utility applications,such as reduced size and weight,with high efficiency,improving fire safety,eliminating of oil as an environmental hazard,and a possible fault current limiting feature for enhancing power system dynamics performance This paper briefly summarizes the status of current HTS transformer projects in Europe,Japan and the United States,the basic characteristics,main merits and the remaining technical challenges The design guidelines and further considerations of operation issues for high temperature superconducting transformers in a future power system were also discussed
