Guide for Protective Grounding of Power Lines
 N 1048

Annotation

Overview

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 de-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.

Purpose

This guide suggests several practices, technical information, and safety criteria for temporary protective grounding of power lines during de-energized maintenance. As an IEEE guide, this document does not have mandatory requirements. Following the suggestions in this guide helps to mitigate risks. Reasonable steps are to be taken by users to minimize all risks associated with protective grounding of power lines during de-energized maintenance.
