Overview
GLP

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.

Core Topics and Focus Areas

  • Distribution and Transmission System Grounding
  • Lightning Protection and Performance
  • Substation Grounding
  • Personal Protective Grounding
  • Pipelines Located near T&D Facilities
  • Copper Theft from Grounding Systems
Program Services

  • Networking & Information Sharing

    • Annual face-to-face Business Meetings with webinar call-in options
    • 4-5 conference calls and learning webinars
    • Access to a network of ~1,000 electrical utility peers from around the world

  • Industry Benchmarking

    • Requests for Information where your questions or concerns are circulated to other group
      participants with rapid-fire response rates
    • Internal benchmarking surveys for state-of-the-industry intelligence

  • Collaborative Technical Projects

    • The flexibility to support only those projects which are relevant to your organization, meaning you know exactly, where your research dollars are going
    • Supported by CEATI management, participating utilities and consultants work together across all phases of a project’s life-cycle, ensuring your organization receives practical, high-quality deliverables

  • Unparalleled Return on Investment

    • Ability to split project funding costs with other organizations, resulting in highly-leveraged funding opportunities
    • Reduced pricing on published reports, training courses, and industry-open conferences
