IEEE 1048-2003

This document provides guidelines for grounding methods to protect workers and the public from voltages that might develop in a jobsite during de-energizing maintenance of overhead transmissions and distribution lines.

This document is intented to provide guidance for protective grounding in jobsites during de-energized maintenance of power lines. The primary purpose of protective grounding is to limit the voltage difference between any two accessible points at the worksite to an acceptable value. As an IEEE guide, the purpose of this document is to suggest approaches for protective grounding. This guide does not have mandatory requirements. Following the suggestions in this guide helps to mitigate risks, and users should take all reasonable steps necessary to minimize risks during de-energized maintenance of power lines.

Revision Standard - Superseded. Guidelines for protective grounding methods for individuals engaged in de-energized overhead transmission and distribution line maintenance are provided. This guide also provides information on the sizing and maintenance of protective ground sets. It is a compilation of information on protective grounding practice employed by North American power utilities.
