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.

This guide covers general recommenda tions for the operation, loading, and main tenance of hydro-generators and generator/ motors (pump/turbines), having salient pole rotors and conventional cooling systems (as distinct from conductor-cooling systems). It does not apply to generators having cylindri cal rotors. In this guide, the term hydro-gen erator is used to describe a generator driven bya hydraulic turbine or water wheel.
