High Temperature Superconducting Power Apparatus
Interest in the application of high temperature superconductivity (HTS) to power devices is growing, as a result of major advances in processing materials and the commercial availability of HTS tapes. Our interest in superconductivity dates back to the early 1980s, when we built and tested a model Low Temperature Superconducting (LTS) generator with liquid helium cooling at 4K. Our current focus is on application of HTS to power apparatus. Our recent work has established our position as one of the world leaders in the application of HTS technology, and includes:
HTS cables and terminations:
- Termination concept design and FEA modelling
- Study of dielectrics for cryogenic applications, including liquid nitrogen bubble dynamics and density change streamers and solids.
- FEA modelling and experimental study of self-field and external-field losses.
- 10kVA demonstration HTS transformer design, build and test.
- EPSRC sponsored project to design, build and test a 100kVA HTS demonstration synchronous generator.
- Currently an EPSRC sponsored project to design and build of a HTS coreless rotor generator is active
