Comments on standards Comments for revision of IEEE Standards documents are welcome from any interested party, regardless of membership affiliation

15、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 appropriate supporting comments. Since IEEE standards represent a consensus of con

For this reason, IEEE and the members of its societies and Standards Coordinating Committees are not able to provide an instant response to comments or questions exc

44、pyright 2014 IEEE. All rights reserved. vii Introduction This introduction is not part of IEEE Std 837-2014, IEEE Standard for Qualifying Permanent Connections Used in Substation Grounding. Working Group E9 of the IEEE PES Substations Committee began updating the standard in 2008. This standard has

45、been updated to fulfill a need for standardization of terminology and test requirements for permanent grounding connections. The most significant changes were made to the EMF test criteria that address the connections to above-grade rigid structures and equipment ground pads. Many types of connectio

46、ns are available that may be used as permanent grounding connections even though they were designed for use as power connections. This standard provides a meaningful reproducible test program that will enable connection manufacturers to qualify their products as permanent grounding connections. The

47、users can then be reasonably assured that the qualied permanent grounding connection will be capable of performing satisfactorily over the lifetime of the installation. This standard addresses the parameters for testing grounding connections on copper, steel, copper-bonded steel, copper-clad steel,

48、galvanized steel, and stainless steel. Copyright 2014 IEEE. All rights reserved. viii Contents 1. Overview 1 1.1 Scope . 1 1.2 Purpose 1 2. Normative references 2 3. Definitions 3 4.
