Problems of building turbogenerators with windings made of superconductors and pure metals

The increase of the unit power of machines and power plants as a whole is a characteristic feature of the development of the turbogenerator building. The need for reducing the capital out lays and construction times, decreasing the operating expenses, and increasing the efficiency of the installations are caused by the rapid growth of the power systems. The use of superconductors and pure metals with cryogenic cooling opens new possibilities for progress in the manufacture of large electrical machines.
