Synchronous NEMA Generator Standards

This standard contains general requirements and definitions applicable to all types of 60-Hz synchronous machines, except fractional horsepower motors. Specific requirements for salient-pole synchronous generators will be found in ANSI C50.12, cylindrical-rotor...

The requirements in this standard apply to all types of 50 Hz and 60 Hz salient-pole synchronous generators and generator/motors rated 5 MVA and above to be used for hydraulic turbine or hydraulic pump/turbine applications. Salient-pole generators and...

Inclusions The requirements in this standard apply to polyphase induction motors intended for use in power generating stations, including the following: a) Frame size larger than NEMA 440 series b) Squirrel-cage type c) Single speed or multispeed d) Horizontal or vertical construction e)...

The requirements in this standard apply to all 50 Hz and 60 Hz, two-pole and four-pole, cylindrical-rotor synchronous generators driven by steam turbines and/or by combustion gas turbines. The drive may be direct or through a gearbox or other device that permits different speeds for...

This Standard specifies the terms and definitions related to the use of synchronous belt and synchronous pulley for mechanical power transmission and where positive indexing or synchronization is required. NOTE The International Standard corresponding to this Standard and the symbol...

This signal generator generates a highly stable, continuous wave (CW), and modulated signal. The unit generates amplitude modulation (AM), frequency modulation (FM), phase modulation (ØM), and pulse modulation (PM) signals with internal or external signals for modulation on demand as...

This guide covers general-purpose synchronous motors without excited rotor windings, including polyphase alternating-current permanent magnet motors rated 500 horsepower and less, designed in standard ratings with standard operating characteristics and mechanical construction for use under...

This document specifies the terms and definitions related to the use of synchronous belt drives for mechanical power transmission and where positive indexing or synchronization is required.

This guide contains instructions for modeling synchronous machines in direct- and quadrature-axis equivalent circuits, along with the basic transient and subtransient reactance/time-constants model in view of stability studies. It discusses assumptions made in using various models and...

This publication provides recommendations for the selection, installation, and use of rotating electric machines in such a manner as to provide for the practical safeguarding of persons and property. Excluded from the scope of this publication are the following: a) Welding generators. b)...

Analysis of Synchronous Machines, Second Edition is a thoroughly modern treatment of an old subject. Courses generally teach about synchronous machines by introducing the steady-state per phase equivalent circuit without a clear, thorough presentation of the source of this circuit...

This International Standard specifies the principal characteristics of synchronous pulleys for use in synchronous endless belt drives for mechanical power transmission and where positive indexing or synchronization is required. NOTE These drives have been known under various names in...

The scope of this document is to provide the basic factors and general considerations in selecting the class and means of neutral grounding for synchronous generator systems connected to electrical utility systems. It also provides the suggested methods and apparatus to be used to...

The requirements in this standard apply to all types of 60-hertz salient-pole synchronous generators and generator motors rated 5000 kVA (kilovolt amperes) and above to be used for hydraulic turbine or hydraulic pump turbine applications. Definitions, characteristics, and test...

This standard defines a new transfer protocol, based upon source synchronous concepts, that currently permits the VMEbus to operate at rates up to 320MB/sec.

FOREWORD Hydraulic-turbine-driven generators, because of their physical size, are usually shipped in several parts and are completely assembled for the first time when they are installed in the power house. The installation, then, becomes a continuation of the manufacturing process, and many...

This part of IEC 60034 applies to large three-phase synchronous generators, having rated outputs of 10 MVA and above driven by steam turbines or combustion gas turbines. Also included are synchronous Mvar compensators of the same output range connected to a grid for the purpose...
