The existence of an IEEE Standard does not imply tha

When the need for interpretations is brought to
15、 the attention of IEEE, the Institute will initiateaction to prepare appropriate responses. Since IEEE Standards represent a consensus of all concerned interests, it isimportant to ensure that any interpretation has also received the concurrence of a balance of interests.

19、cause of operational upset or product failure inindustrial and residential systems and equipment. These problems have received increased attention in recent yearsbecause of the widespread application of complex semiconductor devices that are more sensitive to voltage surges thanvacuum tubes, relays,
20、 and earlier generations of semiconductor devices.Logical and economical design of circuits to protect vulnerable electronic systems from upset or failure requiresknowledge of or an estimate of:1) Transient voltage and current waveforms,2) Frequency of occurrence of transients with various energy le
21、vels,3) Particular environmental variations such as amplitudes, and4) Upset or failure threshold of the particular equipment to be protected.The previous edition of this document, IEEE C62.41-1980, “IEEE Guide for Surge Voltages in Low-Voltages ACPower Circuits” (also known as IEEE Std 587-1980), co
22、ntained similar information about the surge environment.Most of the voltage surge recordings for the 1980 edition were made prior to 1975, when electronic instrumentation forsurge monitoring was not readily available. Instrumentation and data-base information, while still limited in someparameters s
23、uch as very short rise time and frequencies, have vastly improved, as reflected in this edition.This document provides updated and expanded information relevant to a typical surge environment based uponlocation within the building, power-line impedance to the surge, and total wire length. Other para
24、meters often addingto the surge environment include proximity and type of other electrical loads, type of electrical service, wiring quality,and geographic location.New information on probability of surges has been added. A new waveform incorporating a shorter front and two newwaveforms incorporatin
25、g longer durations supplement the two standard waveforms. A new section consisting of a“how-to-use” guide has also been added to allow the reader to develop a rational approach to equipment protection byfollowing the recommendations of this document.It must be noted that a recommendation of test wav
26、eforms alone is not an equipment performance specification. Otherdocuments based on the waveforms recommended herein have been or will be developed to describe the performanceof equipment or protective devices in low-voltage ac power circuits.Some manufacturers have advertised that their protective
27、device “meets the requirements” of IEEE Std 587-1980 orIEEE C62.41-1980. Such a statement is a misuse of the document, since the document only describes surges and doesnot specify any specific safe level or performance of equipment during application of a test waveform. The levels givenin this docum
28、ent reflect typical environment conditions and provide a menu from which equipment designers andusers can select the values appropriate to a specific application. Any statement that a protector “meets the requirementsof” or “is certified to” this document is inappropriate and misleading.The Summary
29、given after this Foreword is intended only for a rapid overview and therefore is not included as part ofthe recommended practice.Suggestions for improvements of this recommended practice will be welcomed.

42、 Power Circuits.)This document describes the occurrence of surges in low-voltage ac power circuits and provides guidance on thesimplification of a complex data base into a limited set of representative surges. This simplification will assistdesigners of equipment in providing the appropriate degree
43、of withstand capability in their designs, allow users ofequipment to specify appropriate levels of withstand requirements, and provide test equipment suppliers and testlaboratories with a recommended practice for a limited number of well-defined test waveforms.Protection from surge voltages in ac po
44、wer circuits can best be achieved through the application of protective devicesmatched to the environment and to the operational requirements of the equipment. Environmental conditions can berepresented by two selected voltage-current waveforms, described as standard waveforms, with amplitude andava
45、ilable energy dependent upon the pertinent location within the power system or distance from the surge source.Circumstances may be encountered where other waveforms, described as additional waveforms, may be appropriate torepresent surges caused by less frequent mechanisms or by the presence of equi
46、pment recognized as the cause oflonger or shorter disturbances.Standard WaveformsFor practical purposes, locations are divided into three categories. Surge characteristics, that is, rates of occurrence,waveforms, source impedances, and amplitudes, are discussed for each category of location and expo
47、sure.1) Locations Category A: Long branch circuits, receptacles (indoor)Category B: Major feeders, short branch circuits, service panel (indoor)Category C: Outdoor overhead lines, service entrance2) Exposure Low Exposure: Systems in geographical areas known for low lightning activity, with little lo
48、ad-switchingactivity.Medium Exposure: Systems in geographical areas known for medium to high lightning activity, or withsignificant switching transients, or both.High Exposure: Those rare installations that have greater surge exposure than those defined by Low Exposureand Medium Exposure.viii3) Reco
49、mmended Values Recommended values are given for the waveforms, voltage amplitude, and current amplitude ofrepresentative surges in line-to-neutral, line-to-line, and neutral-to-ground configurations.Additional WaveformsSpecial situations have been identified in which additional waveforms may be appropriate; these have been added tothe standard waveforms initially defined in the 1980 version of this document. These special situations include thepresence of large banks of switched capacitors or the operation of fuses at the end of long cables. These cases warrantconsideration of a
