| Research Abstract |
Following studies were carried out.
1 Development of 50/60 Hz Superconductor
Starting study of unit superconductor, a rectangular superconductor with dimension 0.35x2.0 and Ic=220 Amp. at 1 T.was developed.
2 Study of A.C. superconducting winding design technique
Using above superconductor, 2 trial windings were made. By these, a relationship between stability and coling condition was studied.
3 Fowllowing feasibility study of large supercoducting machines was carried out
(a) Auto-transformer:/ <phi> -60Hz-1750mva/3-1100/550kv with 3ry wdg. (b) Generator: 2poles-1120mva armature dia.x length; 1200 x 2000
4 Trial making of small superconducting transformers
Through trial making, coil winding techniqe, stability, transient phenomena etc were studied.
5 Conclusion
It is confirmed that the study on supercoducting A.C.machines is useful.
