Development and test of a 100 kVA superconducting transformer operated at 77 K.

Author(s) : KUMMETH P., SCHLOSSER R., MASSEK P., et al.

Summary

High-temperature superconducting (HTS) transformers are very promising candidates for application in electrical power engineering. Their main advantages are: reduced size, weight, better efficiency and reduced potential fire and environmental hazards. The authors have designed, constructed and tested a 100 kVA HTS power transformer operated at 77 K. The nominal primary and secondary currents (voltages) are 18 A (5.6 kV) and 92 A (1.1 kV), respectively. No-load tests, short-circuit tests and load tests proved repeatedly that the transformer has the rated capacity. HTS winding losses of 20.6 W and iron losses of 403 W were measured.
