End-winding region configuration of an HTS transformer
IEEE Transactions on Appiled Superconductivity, 2002Single-phase 14 kVA transformer model with Bi-2223 superconducting windings in a nonmetallic cryostat has been designed and fabricated. Rated voltage of the primary and the secondary winding is 400 V and 200 V, respectively. Considerable attention was paid to the minimization of the radial component of the magnetic field at the end of the winding ...

Design of Current Lead for 50MVA HTS Transformer
Advanced Materials Research, 2014Compared with the conventional transformer, high temperature superconducting (HTS) transformer can effectively improve the efficiency of the system. The current lead of HTS transformer is a main part that leads to leak out heat, and its thermal leakage loss greatly influents the performance of cryogenic system. So it is important to design and optimize

Three-phase modeling of HTS transformer in distribution networks
2010 Conference Proceedings IPEC, 2010Transformers utilizing high temperature superconductors (HTS) are considered as a timely invention. The number of power transformers age more than 30 years old and nearing retirement is increasing. If this window of opportunity is not grabbed, there would be great reluctance to replace recently installed highly priced capital asset.

Multiphysics Approach in HTS Transformers With Different Winding Schemes
IEEE Transactions on Applied Superconductivity, 2014This paper elaborates the results of our previous study by delving into time-step multiphysical simulations juxtaposing electromagnetic and thermal characteristics of a high-temperature superconducting (HTS) transformer. This is attainable by using multiphysical coupling of the Kirchhoff laws, the Maxwell equations, and thermal equilibrium.
