Technique of electrical and hydraulic testing of hydroelectric units

The application of the AIEE Test Code for Synchronous Machines in field testing of hydroelectric generators is discussed, and the preferred method of making certain tests is indicated, together with reasons for its selection. Methods of making acceptance tests on turbines are outlined in sufficient detail to establish the fundamental theory, and the electrical measurements on the generator required to establish the generator input for the hydraulic test, are listed, with brief reference to the accuracy required, and to means of obtaining it. Rating and other hydraulic tests on hydro-electric units are also described.
