Overview
GL

Grounding systems are installed throughout power and telecommunication systems to dissipate energy under lightning, fault and steady-state conditions.

Today there is a greater awareness and desire to ensure that grounding for safety is achieved. There is also a stronger focus on improving lightning performance of transmission and distribution systems.

Grounding issues across the world have typically been dealt with by technical groups, each with their own specific terms of reference. The Grounding & Lightning program takes a broad spectrum view, providing clarity and understanding to grounding and lightning related topics. It provides an avenue for moving information from one technical area to another through peer-to-peer guidance and an opportunity to network, as well as defining the direction for future research.

Target audience:

Cross Utility grounding and lightning engineers, managers, specialists, technologists, safety managers and other specialists who are interested in all grounding and lightning applications.
