Determination of short-circuit torques in turbine generators by test

THE consideration of short-circuit stresses in turbine-generator shafts and frames must be preceded by a knowledge of the developed electrical torque. The theoretical work for this subject has been done by Kilgore and Stone, and Nickle, Pierce and Henderson. As far as is known there have been no extensive measurements of short-circuit torques on modern turbine generators. The object in performing these experiments was to obtain data to check previous equations derived from theoretical considerations and, if necessary, make revisions.
