IEEE 1048a-2021 PDF

The scope remains unchanged from IEEE 1048-2003 and is as follows: This document provides guidelines for grounding methods to protect workers and the public from voltages that might develop in a jobsite during de-energized maintenance of overhead transmission and distribution lines. 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. Amendment Standard - Active. Guidelines are provided for Temporary Protective Grounding (TPG) of electric power lines to assist in 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 include isolation and insulation. These methods are described in other documents and guides and are not discussed here.
