15、terested party, regardless of membership 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 comme

For this reason, IEEE and the members of its societies and Standards Coordi-nating Committees are not able to

17、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.

43、Power Lines.This revision of IEEE Std 1048 is the first revision since the revision in 2003. The Working Group determined the guide needed a common method for evaluating different temporary protective grounding methods, more detailed explanation of electric and magnetic field induction, clarificatio

44、n on the definition of equipotential zones (EPZ), and example calculations for realistic temporary protective grounding work scenarios.An equipotential zone (EPZ), with respect to protective grounding, is relative to the exposure voltage and tolerable current of the worker. Any arrangement of tempor

45、ary protective grounds that achieves limiting ex-posure voltages to allow less current through the worker (in a defined work area) than the tolerable current is considered to create an EPZ. This is obtainable by worksite grounding, bracket grounding, and combination grounding as is described by the

46、Guide, and performed safely in the industry.Worksite grounding, bracket grounding, and combination grounding are different arrangements of temporary protective grounding commonly used in industry due to specific types of repairs and maintenance required on a line. The intent of the guide is to ensur

47、e the safety of the worker drives the temporary protective grounding procedures. Appendix B is included as a normative reference to compare these grounding arrangements to one example of a worksite.This guide was developed through the collaborative effort of an international group of volunteers with

48、 exper-tise in many disciplines. While this guide represents a consensus among this volunteer group, it is not the only view on the issues addressed herein. As with any guidance, use of this guide and the procedures and positions herein does not proof or guarantee safety. Use and compliance with thi

49、s IEEE guide are wholly voluntary.9Copyright 2016 IEEE. All rights reserved.Contents1. Overview . 101.1 Purpose . 102. Normative references 103. Definitions . 114.
