IEEE Guide for Operation and Maintenance of Hydro-Generators

General recommendations are provided for the operation, loading, and maintenance of hydro-generators and generator/motors (pump/turbines), having salient pole rotors and conventional cooling systems (as distinct from conductor cooling systems). The term hydro-generator refers to a generator driven by a hydraulic turbine or waterwheel. Types of units and bases of rating are included. Generators with cylindrical rotors are not covered.
