IEEE 492:1974 (R1986)

New IEEE Standard - Inactive-Withdrawn.
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 recommenda­tions 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). It does not apply to generators having cylindri­cal rotors. In this guide, the term hydro-gen­erator is used to describe a generator driven by
a hydraulic turbine or water wheel.
