Superseded Standard

IEEE 421.4-2004

IEEE Guide for the Preparation of Excitation System Specifications

This guide is intended to provide to the specification writer the information to prepare a specification for the purchase of an excitation system. This guide is presented in narrative form with descriptions of functions typical of excitation systems. Narrative is provided describing types of excitation systems and information required for sizing the excitation system.

IEEE Recommended Practice for the Specification and Design of Field Discharge Equipment for Synchronous Machines

This document is intended to serve as basic reference for the specification and design of field discharge circuits for synchronous machines. It is also intended to provide detailed information about field discharge that complements standards u201cIEEE 421.4.-2004 Guide for Preparation of Excitation System Specificationu201d and includes many aspects of the withdrawn standard u201cANSI/IEEE C37.18.1979 Standard Enclosed Field Discharge Circuit Breakersu201d. This document shows the most employed field discharge circuits and defines the main design criteria and conditions for the main components of field discharge circuit for synchronous machines.

421.1-1986

IEEE Standard Definitions for Excitation Systems for Synchronous Machines

Elements and commonly used components in excitation control systems and for excitation systems as applied to synchronous machines are defined. The primary purpose of the standard is to provide a vocabulary for writing excitation systems specifications, evaluating excitation system performance, specifying methods for excitation system tests, and preparing excitation system standards. It is also intended to serve as an educational aid for those becoming acquainted with excitation systems.

421.3-1997

IEEE Standard for High-Potential Test Requirements for Excitation Systems for Synchronous Machines

High-potential test voltages for excitation systems used with synchronous machines are established. Test voltages are established based on whether equipment is connected to the exciter power circuit or is electrically isolated from the exciter power circuit.
