CoordinatingCommittees of the IEEE Standards Association(IEEE-SA)Standards Board.The IEEE develops its standardsthrough a consensus development process,approved by the American National Standards Institute,which bringstogether volunteers representing varied viewpoints and interests to achieve the final product.Volunteers are notnecessarily members of the Institute and serve without compensation.While the IEEE administers the process andestablishes rules to promote fairness in the consensus development process,the IEEE does not independentlyevaluate,test,or verify the accuracy of any of the information contained in its standards.Use of an IEEE Standard is wholly voluntary.The IEEE disclaims liability for any personal injury,property orother damage,of any nature

that there are no other ways to produce,test,measure,purchase,market,or provide other goods and services related to the scope of the IEEE Standard.Furthermore,theviewpoint expressed at the time a standard is approved and issued is subject to change brought about throughdevelopments in the state of the art and comments received from users of the standard.Every IEEE Standard issubjected to review at least every five years for revision or reaffirmation.When a document is more than fiveyears old and has not been reaffirmed,it is reasonable to conclude that its contents,although still of some value,do not wholly reflect the present state of the art.Users are cautioned to check to determine that they have the latestedition of any IEEE Standard.In publishing and making this document

to the attention of IEEE,the Institute willinitiate action to prepare appropriate responses.Since IEEE Standards represent a consensus of concernedinterests,it is important to ensure that any interpretation has also received the concurrence of a balance ofinterests.For this reason,IEEE and the members of its societies and Standards Coordinating Committees are notable to provide an instant response to interpretation requests except in those cases where the matter has previouslyreceived formal consideration.At lectures,symposia,seminars,or educational courses,an individual presentinginformation on IEEE standards shall make it clear that his or her views should be considered the personal views ofthat individual rather than the formal position,explanation,or interpretation of the IEEE.Comments for revision of IEEE Standards are welcome from any interested party,regardless of membershipaffiliation with IEEE.Suggestions for changes in documents should be in the form of a proposed change of text,together with appropriate supporting comments.Comments on standards and requests for interpretations shouldbe addressed to:Secretary,IEEE-SA Standards Board445

tutorial in nature as it is intended to provide guidance in the design of electric powerservice systems for electric power generation plants.The guidance and direction given in this guide is,forthe most part,general in nature and is applicable to all types and sizes of electric power generating plants.This guide does not provide unique and specific design direction and guidance for special systems in thevarious types of electric power generating plants,but rather provides the basic framework upon which anyrequired unique and specific designs can be built.An electric power service system consists of a mainauxiliary power distribution network,which may supply many subsystems such as electric trace heatingsystems,dc systems,Class 1E power systems,etc.It is recommended that the reader consult industrystandards that address these specific subsystems in more detail as appropriate during the design process.This design guide was prepared by the Working Group on Auxiliary Systems,which is part of the StationDesign Subcommittee of the Energy Development and Power Generation Committee of the IEEE PowerEngineering Society.This revision includes primarily editorial changes needed to maintain consistency with phraseology andterminology changes that have been made in other referenced standards and documents and to correcttypographical errors in the 1991 edition of this guide.It also includes only relatively minor technicalchanges.Notice to usersErrataErrata,if any,for this and all other standards can be accessed at the following

patent rights.By publication of this standard,no position is taken with respect to the existence orvalidity of any patent rights in connection therewith.The IEEE shall not be responsible for identifyingpatents or patent applications for which a license may be required to implement an IEEE standard or forconducting inquiries into the legal validity or scope of those patents that are brought to its attention.This introduction is not part of IEEE Std 666-2007,IEEE Design Guide for Electric Power Service Systems forGenerating Stations.Authorized licensed use limited to:New York
