Superconducting transformers

The technological progress of power frequency ac superconductor is remarkab le and application studies are being carried out, targeting ac super-conduc ting (SC) machines for power systems. The introduction of SC machines into the power system, needs to display the merits of not only efficiency improv ement but also power system performance and operation. A conceptual design for a coreless super-conducting transformer (SCT) is made, based on the abo ve views and it's merits evaluated. A future possible power system employin g coreless SCT's is presented, and consideration is given to the actual ser vice in a future power system.
