50 Hz or 60 Hz synchronous generators driven by diesel engines, steam turbines, combustion gas turbines, and hydro-turbines are covered in this guide. The drive may be direct or through a gear box or other device that permits different speeds for the prime mover and the generator. The guide generally applies to the stator and rotor of generators with rated outputs of 1 MVA and above. The guide does not address machine auxiliaries or the excitation system. This guide will provide the generator Owner with insight into the considerations that are necessary when rewinding or refurbishing a generator. Particular emphasis is placed on the complete rewind of the stator and rotor. Keywords: cylindrical-pole rotor, insulation, rotor rewind, salient-pole rotor, stator rewind, synchronous generator.

The standards in this section apply to the following types of rotating machines: 1. induction motors larger than fractional horse power; 2. induction generators, they are applicable also to induction machines in general. Alternating-current commutator motors are not covered in detail but they shall conform to these Standards as regards ratings, temperature rises and dielectric tests.

A basic philosophy and guidelines are established for the design and implementation of monitoring systems for cylindrical-rotor, synchronous turbine generators. Monitoring systems are used to display the status of the generator and auxiliary systems while these systems are operating on line. The basic information needed to choose monitoring schemes best suited for each application is provided. This standard does not specify actual equipment or instrumentation, but it does indicate some critical areas where it is important to provide monitoring capability.

Instructions are given for conducting and reporting the more generally applicable and acceptable tests to determine the performance characteristics of single phase induction motors. Electrical measurements, performance testing, temperature tests, and miscellaneous tests are covered.

Instructions for conducting generally applicable and accepted tests to determine the performance characteristics of synchronous machines are contained in this guide. Although the tests described are applicable in general to synchronous generators, synchronous motors (larger than fractional horsepower), synchronous condensers, and synchronous frequency changers, the descriptions make reference primarily to synchronous generators and synchronous motors.

The application of standstill frequency response testing methods for obtaining direct- and quadrature-axis stability parameters is described. Measurable parameters at standstill are discussed, and the test method is described. This standard is a supplement to ANSI/IEEE Std 115-1983, IEEE Guide: Test Procedures for Synchronous Machines.

This standard defines elements and commonly used components in excitation systems and contains definitions for excitation systems applied to synchronous machines. An included annex contains one-line block diagrams of some typical excitation systems. These are presented to illustrate the defined terminology referenced in this standard and clarify the understanding of the excitation control system.
