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

Comments on standards Comments for revision of IEEE Standards documen
17、ts are welcome from any interested party, regardless of membership affiliation with IEEE. However, IEEE does not provide consulting information or advice pertaining to IEEE Standards documents. Suggestions for changes in documents should be in the form of a proposed change of text, together with app
18、ropriate supporting comments. Since IEEE standards represent a consensus of concerned interests, it is important that any responses to comments and questions also receive the concurrence of a balance of interests. For this reason, IEEE and the members of its societies and Standards Coordinating Comm
19、ittees are not able to provide an instant response to comments 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 welcom

Updating of IEEE Standards documents Users of IEEE Standards documents should be aware that these documents may be superseded at any time by the issuance of new editions or may be amended from time to time through the issuance of amendments, corrigenda, or errata. An official IEEE do
27、cument 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 ten years. When a document is more than ten years old and has not undergone a revision process, it
28、 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 latest edition of any IEEE standard. In order to determine whether a given document is the current edition and
29、whether it has been amended through the issuance of amendments, corrigenda, or errata, visit the IEEE-SA Website at http:/ieeexplore.ieee.org/xpl/standards.jsp or contact IEEE at the address listed previously.

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 appli
32、cant has filed a statement of assurance via an Accepted Letter of Assurance, then the statement is listed on the IEEE-SA Website at http:/standards.ieee.org/about/sasb/patcom/patents.html. Letters of Assurance may indicate whether the Submitter is willing or unwilling to grant licenses under patent
33、rights without compensation or under reasonable rates, with reasonable terms and conditions that are demonstrably free of any unfair discrimination 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
34、 responsible 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
35、in any licensing agreements are reasonable or non-discriminatory. Users of this standard are expressly advised that determination of the validity of any patent rights, and the risk of infringement of such rights, is entirely their own responsibility.

45、ii Introduction This introduction is not part of IEEE Std 1653.6-2013, IEEE Trial-Use Recommended Practice for Grounding of DC Equipment Enclosures in Traction Power Distribution Facilities. This document contains recommended practices for grounding and bonding of dc equipment enclosures installed w
46、ithin traction power distribution facilities where the conventional practice in most dc traction power systems is to isolate both the positive and negative poles from ground. There exists a variety of system grounding methods, including single-point grounding, positive- or negative-pole grounding, r
47、esistive grounding, diode grounding, etc; however, details on system grounding and related applications, e.g., stray current control, rail-to-ground protective relay devices, are not covered by the scope of this document. For additional information regarding transit power systems grounding, refer to
48、 IEEE Std 142, IEEE Recommended Practice for Grounding of Industrial and Commercial Power Systems.a,b,cThe necessity of this recommended practice stems from the lack of uniformity of enclosure grounding practices in the dc traction industry. Furthermore, grounding of dc traction equipment enclosures
49、 is not covered in the National Electric Code B4dand National Electrical Safety Code B2. As such, the goal of this document is to provide users with the various grounding methods used specifically for grounding dc traction equipment enclosures and preparing dc traction distribution facilities when implementing these grounding methods. The organization of this document follows a typical equipment layout within a dc traction distribution facility. The main sections include ac equipment enclosures, dc equipment enclosures, floor insulation, and wall insulation. Refer to
