IEEE P1048-D10-2015 pdf free.IEEE P1048 TM/D10 Draft Guide for Protective Grounding of Power Lines.
This document provides guidelines for temporary protective grounding of electric power lines to aid in the protection of workers from voltages and currents that might develop at a dc-energized worksite during maintenance of AC overhead and underground. transmission and distribution lines, cables and equipment.
Other forms of worker protection including isolation and insulation are acceptable methods, when used properly, in the place of temporary protective grounding. Details of these other methods are described in other documents and guides and are not further discussed here.
This guide suggests several practices, technical information, and safety criteria for temporary protective grounding of power lines during de-energized maintenance. As an lEEk guide, this document does not have mandatory requirements. Following the suggestions in this guide helps to mitigate risks. Reasonable steps arc to be taken by users to minimize all risks associated with protective grounding of power lines during dc-energized maintenance.

For the purposes of this documcnt. ihc following terms and definitions apply. The IEEE Standard.s Dictionary. Glossary of Terms Deli nmons’ can he referenced for terms not defined in this clause.
Bonded; the mechanical interconnection of conductive parts to maintain a common electrical potential (See: Bonding, IEEE Std. 100 [B8].) Synonym: connected.
Bracket grounding; a grounding method with temporary protective ground sets installed on both sides of a
work site one structure or more away from the worksite.
See Figure 9.
Bundled: One phase of a circuit formed from multiple conductors. Each conductor of the phase is referred to as a suh-conductor
Clamp: A device used in making a temporary connection between the grounding cable and the ground bus or grounding electrode, and between the grounding cable and the phase or equipment being grounded.
Cluster bar: a portable device attachcd to a pole or structure as a means for bonding and connecting temporary protective grounds. Synonym: pole band.
Combination grounding: a grounding method where temporary protective ground sets arc installed as bracket grounds with an additional personal ground set installed at the changing work site on the phase being worked. See Figure 10.
Conductor: a wire or combination of wires stranded together not insulated from one another, suitable for carrying an electric current. Ii may be bare or insulated, Synonyms: cable: wire.
Dc-energized: Disconnected from all intentional sources olelectrical supply by opening switches, jumpers. Laps, elbows or other means. Deenergized conductors and objects can be electrically charged or energized through various means. c. g. induction from energized circuits, or lightning.
Electric field induction (c’apncithe coupling): the process of generating a voltage or current in an isolated conductive object or electric circuit by means of capacitive coupling between the energized circuit and conductive object and between the conductive object and earth.
Electromagnetic field induction (electromagnetic coupling): the process that employs both electric and magnetic fields to generate a circulating current between two grounded sites of a line due to the proximity olan adjacent or nearby energized line.IEEE P1048-D10 pdf download.
