How Lightning Influences Power System Design

Lightning is fast, unpredictable, and electrically complex. For transmission lines and substations, its effects can show up as insulation stress, flashover risk, equipment exposure, and reliability challenges that are not always obvious from the strike itself.

In this webinar, presenter and Commonwealth Protection and System Studies Engineer, Kitt Connor, P.E. will move beyond general lightning protection concepts to explain the physics behind how lightning interacts with power systems and how engineers translate those effects into practical transmission and substation design decisions.

Designed for utility leaders, project managers, buyers, and technical teams, the session offers a concise, approachable look at lightning performance studies, electromagnetic transient behavior, and the engineering insight needed to reduce risk and strengthen long-term system reliability.

By attending this webinar, participants will learn to:

  • Explain how lightning physics affects transmission and substation assets.
  • Understand how lightning studies support insulation, shielding, grounding, and reliability decisions.
  • Describe how engineers use data, models, and study results to evaluate performance.
  • Recognize how transient tools and engineering judgment guide mitigation strategies.


Registration is now open.

Frequently Asked Questions About Lightning Studies


What is a lightning study?

A lightning study evaluates how lightning may affect transmission lines, substations, and other electrical infrastructure. Engineers use these studies to assess system performance, identify risks, and support reliable power system design.

Why are lightning studies important for utilities?

Lightning can contribute to insulation stress, flashovers, equipment exposure, and reliability challenges. Understanding these impacts helps utilities make informed planning, design, and asset protection decisions.

How do engineers analyze lightning performance?

Engineers use system models, transient analysis tools, performance studies, and engineering judgment to evaluate how lightning events may affect power system assets and operations.

How can lightning affect transmission and substation systems?

Lightning creates fast, high-energy electrical transients that can stress insulation systems, impact equipment performance, and influence overall system reliability.

What engineering decisions can lightning studies support?

Lightning studies can inform insulation coordination, shielding design, grounding strategies, equipment protection measures, and reliability improvement initiatives.

When should a utility perform a lightning study?

Utilities often perform lightning studies when planning new transmission lines or substations, evaluating existing infrastructure, investigating reliability concerns, or assessing major system modifications.
