Lightning & Grounding Considerations for Overhead Line Rebuilding and Refurbishing Projects, AC and DC

Overhead lines age naturally or may reach premature end-of-life. Motivations for rebuilding or refurbishing lines have included reliability (poor lightning performance), thermal rating, component end-of-life, reduced visual impact and right-of-way encroachment (grounding). The Brochure adds value to redesign projects, promoting synergies among disciplines and developing alternatives that improve, or at least do not degrade, lightning performance while satisfying other objectives.
