1、Recommended Practice for Motor Protection in Industrial and Commercial Power Systems IEEE Std 3004.8 -2016 IEEE 3004 STANDARDS: PROTECTION fitness for a particular purpose; non-infringement; and quality, accuracy, effectiveness, currency, or completeness of material. In addition, IEEE disclaims any
2、and all conditions relating to: results; and workmanlike effort. IEEE standards documents are supplied “AS IS” and “WITH ALL FAULTS.” Use of an IEEE standard is wholly voluntary. The existence of an IEEE standard does not imply that there are no other ways to produce, test, measure, purchase, market
3、, 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 is subject to change brought about through developments in the state of the art and comments received from users of the standard. In pub
4、lishing and making its standards available, IEEE is not suggesting or rendering professional or other services for, or on behalf of, any person or entity nor is IEEE undertaking to perform any duty owed by any other person or entity to another. Any person utilizing any IEEE Standards document, shoul
5、d rely upon his or her own independent judgment in the exercise of reasonable care in any given circumstances or, as appropri- ate, seek the advice of a competent professional in determining the appropriateness of a given IEEE standard. IN NO EVENT SHALL IEEE BE LIABLE FOR ANY DIRECT, INDIRECT, INCI
6、DENTAL, SPECIAL, EXEMPLARY , OR CONSEQUENTIAL DAMAGES (INCLUDING, BUT NOT LIMITED TO: PROCURE- MENT OF SUBSTITUTE GOODS OR SERVICES; LOSS OF USE, DATA, OR PROFITS; OR BUSINESS INTERRUPTION) HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY , WHETHER IN CON- TRACT, STRICT LIABILITY , OR TORT (INCLUDING N
7、EGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE PUBLICATION, USE OF, OR RELIANCE UPON ANY STANDARD, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGE AND REGARDLESS OF WHETHER SUCH DAMAGE WAS FORESEEABLE.4 Copyright 2017 IEEE. All rights reserved. Translations The IEEE consensus development pr
8、ocess involves the review of documents in English only. In the event that an IEEE standard is translated, only the English version published by IEEE should be considered the approved IEEE standard. Official statements A statement, written or oral, that is not processed in accordance with the IEEE-SA
9、 Standards Board Operations Manual shall not be considered or inferred to be the official position of IEEE or any of its committees and shall not be considered to be, or be relied upon as, a formal position of IEEE. At lectures, symposia, seminars, or educational courses, an individual presenting in
10、formation on IEEE standards shall make it clear that his or her views should be considered the personal views of that individual rather than the formal position of IEEE. Comments on standards Comments for revision of IEEE Standards documents are welcome from any interested party, regardless of membe
11、rship affiliation with IEEE. However, IEEE does not provide consulting information or advice pertain- ing to IEEE Standards documents. Suggestions for changes in documents should be in the form of a proposed change of text, together with appropriate supporting comments. Since IEEE standards represen
12、t a consensus of concerned interests, it is important that any responses to comments and questions also receive the concur- rence of a balance of interests. For this reason, IEEE and the members of its societies and Standards Coordi- nating Committees are not able to provide an instant response to c
13、omments or questions except in those cases where the matter has previously been addressed. For the same reason, IEEE does not respond to interpretation requests. Any person who would like to participate in revisions to an IEEE standard is welcome to join the relevant IEEE working group. Comments on
14、standards should be submitted to the following address Secretary, IEEE-SA Standards Board 445 Hoes Lane Piscataway, NJ 08854 USA Laws and regulations Users of IEEE Standards documents should consult all applicable laws and regulations. Compliance with the provisions of any IEEE Standards document do
15、es not imply compliance to any applicable regulatory require- ments. Implementers of the standard are responsible for observing or referring to the applicable regulatory requirements. IEEE does not, by the publication of its standards, intend to urge action that is not in compliance with applicable
16、laws, and these documents may not be construed as doing so. Copyrights IEEE draft and approved standards are copyrighted by IEEE under US and international copyright laws. They are made available by IEEE and are adopted for a wide variety of both public and private uses. These include both use, by r
17、eference, in laws and regulations, and use in private self-regulation, standardization, and the pro- motion of engineering practices and methods. By making these documents available for use and adoption by public authorities and private users, IEEE does not waive any rights in copyright to the docum
18、ents.5 Copyright 2017 IEEE. All rights reserved. Photocopies Subject to payment of the appropriate fee, IEEE will grant users a limited, non-exclusive license to photocopy portions of any individual standard for company or organizational internal use or individual, non-commercial use only.

20、enter. Updating of IEEE Standards documents Users of IEEE Standards documents should be aware that these documents may be superseded at any time by the issuance of new editions or may be amended from time to time through the issuance of amendments, corri- genda, or errata. An official IEEE document
21、at any point in time consists of the current edition of the document together with any amendments, corrigenda, or errata then in effect. Every IEEE standard is subjected to review at least every 10 years. When a document is more than 10 years old and has not undergone a revision process, it is reaso
22、nable 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 latest edition of any IEEE standard. In order to determine whether a given document is the current edition and whether i
23、t has been amended through the issuance of amendments, corrigenda, or errata, visit the IEEE Xplore at http:/ ieeexplore .ieee .or g/ or contact IEEE at the address listed previously. For more information about the IEEE-SA or IEEEs standards development process, visit the IEEE-SA Website at http:/ s
24、tandards .ieee .or g. Errata Errata, if any, for all IEEE standards can be accessed on the IEEE-SA Website at the following URL: http:/ standards .ieee .org/ findstds/ errata/ index .html. Users are encouraged to check this URL for errata periodically. Patents Attention is called to the possibility
25、that implementation of this standard may require use of subject matter covered by patent rights. By publication of this standard, no position is taken by the IEEE with respect to the existence or validity of any patent rights in connection therewith. If a patent holder or patent applicant has filed
26、a statement of assurance via an Accepted Letter of Assurance, then the statement is listed on the IEEE- SA Website at http:/ standards .ieee .or g/ about/ sasb/ patcom/ patents .html. Letters of Assurance may indicate whether the Submitter is willing or unwilling to grant licenses under patent right
27、s without compensation or under reasonable rates, with reasonable terms and conditions that are demonstrably free of any unfair discrim- ination to applicants desiring to obtain such licenses. Essential Patent Claims may exist for which a Letter of Assurance has not been received. The IEEE is not re
28、- sponsible for identifying Essential Patent Claims for which a license may be required, for conducting inquiries into the legal validity or scope of Patents Claims, or determining whether any licensing terms or conditions provided in connection with submission of a Letter of Assurance, if any, or i
29、n any licensing agreements are reasonable or non-discriminatory. Users of this standard are expressly advised that determination of the valid- ity of any patent rights, and the risk of infringement of such rights, is entirely their own responsibility.
