Transmission & Distribution Grounding and Stray Voltage

Transmission & Distribution Grounding and Stray Voltage

March 19-20, 2024 | 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 leave the course with a full understanding of this complex network.

Register today and leave this course with a comprehensive understanding of:

  • Necessary grounding methods and practices
  • Stray voltage mitigation techniques
  • With special attention to:
    • Three-phase power systems
    • Step/touch potentials
    • Ground resistance measurements
    • Ground grid
    • 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
  • Identify stray voltage definitions and how stray voltage is measured
  • Analyze stray voltage mitigation techniques, including phase balancing, deteriorated neutrals, and neutral isolators
  • Assess stray voltage scenarios such as swimming pools, farms, fences and more
