5、 developed within the Technical Committees of theIEEE Societies and the Standards Coordinating Committees of the IEEE StandardsBoard. Members of the committees serve voluntarily and without compensation.They are not necessarily members of the Institute. The standards developed withinIEEE represent a
6、 consensus of the broad expertise on the subject within the Instituteas well as those activities outside of IEEE that have expressed an interest in partici-pating in the development of the standard.Use of an IEEE Standard is wholly voluntary. The existence of an IEEE Standarddoes not imply that ther
7、e are no other ways to produce, test, measure, purchase, mar-ket, or provide other goods and services related to the scope of the IEEE Standard.Furthermore, the viewpoint expressed at the time a standard is approved and issued issubject to change brought about through developments in the state of th
8、e art and com-ments received from users of the standard. Every IEEE Standard is subjected toreview at least every five years for revision or reaffirmation. When a document ismore than five years old and has not been reaffirmed, it is reasonable to conclude thatits contents, although still of some va
9、lue, do not wholly reflect the present state of theart. Users are cautioned to check to determine that they have the latest edition of anyIEEE Standard.Comments for revision of IEEE Standards are welcome from any interested party,regardless of membership affiliation with IEEE. Suggestions for change
10、s in docu-ments should be in the form of a proposed change of text, together with appropriatesupporting comments.Interpretations: Occasionally questions may arise regarding the meaning of portionsof standards as they relate to specific applications. When the need for interpretationsis brought to the
11、 attention of IEEE, the Institute will initiate action to prepare appro-priate responses. Since IEEE Standards represent a consensus of all concerned inter-ests, it is important to ensure that any interpretation has also received the concurrenceof a balance of interests. For this reason IEEE and the
12、 members of its technical com-mittees are not able to provide an instant response to interpretation requests except inthose cases where the matter has previously received formal consideration. Comments on standards and requests for interpretations should be addressed to:Secretary, IEEE Standards Boa

15、bove 230 kV Nominal.)This standard supersedes ANSI C92.2-1981, American National Standard Preferred Voltage Ratings forAlternating-Current Electrical Systems and Equipment Operating at Voltages Above 230 kV Nominal. Pre-ferred maximum voltage ratings provide guidance in the development and design of
16、 these systems andequipment. Preferred nominal voltage ratings are included to provide consistent standard designations forelectrical systems in the extra-high and ultra-high voltage classes.This standard includes preferred voltage ratings up to and including 1200 kV maximum system voltage, asdefine
17、d in the standard. Above this value, additional research and development work is needed before stan-dard voltage levels can be specified. It is expected that the next voltage level to be established will be as highas is technically and economically feasible at the time that it is introduced.ANSI C84
18、.1-1982, American National Standard Voltage Ratings for Electric Power Systems and Equipment(60Hz), covers standard system voltages up to and including 230 kV nominal system voltage. The discus-sions in Sections 2 and 3 of ANSI C84.1-19821contain information that should be helpful in achieving stan-
19、dardardization of voltage ratings for alternating-current electrical systems.The following persons were on the balloting committee:J. D. Borst Fred Kimsey N. S. PorterJohn Boyle David G.

24、tandard provides preferred voltage ratings above 230 kV nominal for alternating-current (ac) systemsand equipment.2. DefinitionsNOTEThe definitions given in 2.1 through 2.5 for certain terms relating to voltage ratings for ac systems and equip-ment are intended to clarify the meaning and intent of t
25、his standard.2.1 system voltage:A root-mean-square (rms) phase-to-phase power frequency voltage on a three-phase acelectrical system.2.2 maximum system voltage:The highest rms phase-to-phase voltage that occurs on the system under nor-mal operating conditions, and the highest rms phase-to-phase volt
26、age for which equipment and other systemcomponents are designed for satisfactory continuous operation without derating of any kind.When defining maximum system voltage, voltage transients and temporary overvoltages caused by abnor-mal system conditions such as faults, load rejection, etc., are exclu
27、ded. However, voltage transients and tem-porary overvoltages may affect equipment operating performance and are considered in equipmentapplication.2.3 nominal system voltage:The system voltage by which the system may be designated and to which cer-tain operating characteristics of the system are rel
28、ated.The nominal voltage of a system is near the voltage level at which the system normally operates. To allowfor operating contingencies, systems generally operate at voltage levels about 510% below the maximumsystem voltage for which system components are designed.2.4 extra-high voltage (ehv):A ma
29、ximum system voltage that is greater than 242 kV but less than 1000 kV.IEEE Std 1312-199322.5 ultra-high voltage (uhv):A maximum system voltage that is equal or greater than 1000 kV.NOTEThe classification of ehv and uhv is provided for the purpose of establishing consistency in the use of theseterms, reflecting common usage.3.
