Expanded in this amendment is the use of conductive mats for creating equipotential zones. Specific guidance in the use of conductive mats while applying temporary protective ground cables is provided.

This amendment adds the rigid carrier mat as an alternative option to the fabric carrier mat by adding a new section 9.1. to IEEE Std 1048.

The purpose of this guide is to define practices, technical information, and safety criteria that can be used by utility workers and contractors 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 risks associated with protective grounding of power lines during de-energized maintenance.
