Transmission & Distribution Grounding and Stray Voltage

Transmission & Distribution Grounding and Stray Voltage

March 14-15, 2023 | Online :: Central Time

Matt was awesome. Very knowledgeable and willing to show many different ways to cover all possible testing scenarios for finding stray voltage. Great job.” – QUES

“Course was full of useful information to help potentially find stray voltage and mitigate any problems resulting from it.” – QUES

“Matt was exceptional – knowledgeable, practical and very quick to address questions asked.” – Eversource Energy

The Transmission & Distribution Grounding and Stray Voltage program aims to provide electric engineering professionals and technicians with a contemporary overview of grounding practices and stray voltage issues, helping them to leave the course with a full understanding of this complex network.

Throughout the course attendees will leave with a comprehensive understanding of the necessary grounding methods and practices, as well as the stray voltage mitigation techniques and real-life scenarios. Details will include three-phase power systems, step/touch potentials, ground resistance measurements, ground grids, test equipment, neutral isolators, and more.

Learning Outcomes 

  • Review engineering formulas in order to start a foundational knowledge of grounding (i.e. Ohm’s Law, Kirchhoff’s Voltage & Current Laws, etc.)
  • Discuss grounding methods and definitions, including step/touch potentials, connection points, electrodes, etc.
  • Evaluate grounding practices in the distribution and transmission system (measurements, substation, ground grids, ground design)
  • Examine the effects of electricity on humans and animals
  • Review stray voltage definitions and how it’s measured
  • Analyze stray voltage mitigation techniques, including phase balancing, deteriorated neutrals, and neutral isolators
  • Consider stray voltage scenarios such as swimming pools, farms, fences and more
