HTS transformers

Abstract

The paper elucidates on some of the potential systems benefits and provides an update of progress in major high-temperature superconductor (HTS) transformer development programs worldwide. It begins with background sections on earlier low-temperature-superconductor (LTS) transformer developments and on transformer losses and efficiencies and their influence on total owning costs (TOC) as one of the major drivers that may determine the success and broad acceptance of HTS transformers for power applications.
