Electrical Studies for Design of AC & DC Transmission Lines

September 17, 2026 Online :: Central Time

“EUCI conferences always have industry-leading experts and subject matter experts as speakers. The material presented is very valuable.”

Project Administrator, TECO

This course will provide a focused overview of the electrical considerations and studies involved in overhead AC and DC transmission line design across high voltage (HV), extra high voltage (EHV), and ultra-high voltage (UHV) projects. While civil and structural aspects of design often dominate project engineering effort and cost, electrical studies play a critical role in long-term reliability, system performance, and environmental integration. Through examples, visualization, and summaries of applicable standards and literature, attendees will examine what electrical studies are required, why they matter, and how their results influence design decisions and coordination with civil, structural, and transmission planning disciplines.

Electrical study relevance will be discussed with comparisons between HV (<345 kV), EHV (345-1000 kV), and UHV (>1000kV) AC transmission projects and HVDC projects. Given renewed interest in 765 kV transmission in North America, special attention will be given to how 765 kV electrical performance differs from the more common 345 kV and 500 kV voltage classes. While attendees will not learn to perform electrical studies themselves, they will gain insight needed to plan projects, develop effective proposal specifications, and assess the completeness and appropriateness of electrical studies prepared by others.

Attendees will leave better equipped to scope, review, and coordinate electrical aspects of transmission line projects within multidisciplinary design teams.

Learning Outcomes

Through this course, attendees will:

  1. Review the electrical environment in which transmission lines operate
  2. Discuss electrical studies needed for transmission line design and how these studies link to civil/structural work and other aspects of transmission planning, design, and system integration
  3. Identify key characteristics, applicable standards, and special considerations of transmission line electrical studies
  4. Discuss how electrical study considerations change based on line length and voltage class (with emphasis on 765 kV design considerations)
  5. Review the transmission line design process

Transmission Line Design Overview & Electrical Studies Introduction

This session will provide attendees with an overview of the electrical environment in which a transmission line must operate, a high-level overview of the design process, and a brief introduction to each of the electrical studies covered by the course. These studies include:

  • Transmission line constants
  • Electrical losses
  • Energy capacity
  • Short circuit and protection
  • Insulation coordination (lightning, switching, contamination, CFO, arresters)
  • Shield wire lightning withstand
  • Minimum Approach Distances (MAD)
  • Voltage and current imbalance
  • Electric and magnetic fields
  • Corona effects (audible and radio noise)
  • Hardware corona performance
  • AC interference with adjacent facilities
  • Microshocks and contact current (NESC 5 mA rule)
  • NESC electrical clearances
  • Communications interference
  • Touch and step potential analysis
  • Delayed zero crossings
  • Parallel line resonance

Visualizing Electrical Basics of Transmission Lines

Learn about transmission line electrical characteristics and considerations through exploration of the following studies: Transmission Line Constants, Voltage/Current Imbalance, Electrical Loss, Energy Capacity, Short Circuit/Protection studies, and Delayed Zero Crossing studies.

Transmission Line Electrical Reliability     

Learn how insulation coordination studies strike a balance between flashover performance (reliability) and cost through an examination of switching surge, lightning, and contamination performance. Discuss critical flashover voltage (CFO) and its importance in the larger insulation coordination process. Briefly discuss shield wire lightning withstand and minimum approach distance (MAD) considerations.

Electric and Magnetic Field Related Considerations

Visualize electric and magnetic fields and discuss how their calculation plays an important role in environmental integration of a project. Review audible noise, radio noise, and discuss other corona and health effects. Learn about microshock currents in the context of the NESC 5 mA rule and utility worker microshock exposure when working near high voltage lines. Discuss Hardware Corona Performance studies and important considerations of laboratory testing.

External Interactions

Discuss NESC electrical clearances and identify how transmission line performance can still impact external facilities such as railroads, pipelines, and radio broadcast facilities, even when clearance requirements are met. Discuss in the context of AC Interference, Communications Interference, and Parallel Line Resonance studies. Step and touch potential analysis near transmission structures will also be briefly examined.

765 kV Considerations

Discuss 765 kV-specific electrical design considerations through comparison of study results to 500 kV and 345 kV transmission line examples. Certain studies become less important for 765 kV and others become more important.
