Abstract
Principles which influence the design, application, and operation of conductor-cooled turbine-generators with liquid-cooled stator windings and gap-pickup rotors are defined. Thermal design practice applying for continuous operation at steady-state load conditions is described, and the practical attainment of design temperatures is verified by the results of generator tests in the factory and in the field. Temperature-time relationships resulting from short-time overload conditions are shown. These thermal relationships and the associated duty on the generator components form the basis for a guide to machine operation during forcing conditions and short circuits. Generator thermal characteristics are related to generator and system characteristics which are considerations of proper application and operation of the generator on the power system.Keywords
