Electric Distribution Grounding & Stray Voltage

Electric Distribution Grounding & Stray Voltage

September 29-30, 2021 | Online :: Central Time

“I’m thrilled that I attended Stray Voltage and Grounding course. I feel like I’m going back to my job armed with knowledge to better troubleshoot our stray voltages complaints. I wish I had attended this course years ago.” Electrical Engineer, EnergyUnited EMC

“EUCI organized and coordinated a training class that was well put together and focused on attendees and content.” –Electric Utility Engineer III, City of Tallahassee

“Speakers were well-spoken and entertaining. Appreciated the joke slides between topics, really helped break it up between.” –Power Quality Engineer, CenterPoint Energy

The electric distribution ground system is a complex network of various paths and accommodates the return current back to the substation. The Electric Engineering professionals and technicians who attend will be greeted with a contemporary overview of grounding practices and stray voltage issues and will leave the course with a full understanding of this complex network. Throughout the course, they will be exposed to everything from a review of engineering formulas (Ohm’s Law, Kirchhoff’s Laws, impedance, alternating current) to specific stray voltage situations, allowing them to apply all of the new or reinforced knowledge towards real-world examples.  

This event provides insight into the workings of the grounding system from the end user back to the substation. Attendees learn the causes of high ground currents, how they can be minimized, and the techniques to mitigating stray voltage. They will grasp not just terms and techniques, but how electric distribution grounding can heavily affect their animals, homes, and themselves. Upon completing this program, all attendees who participate will feel comfortable initiating and holding educated and insightful conversations with their colleagues who partake in grounding projects on the day-to-day.

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.)
  • Evaluate different grounding methods and the NESC standards
  • Define important grounding concepts, including effectively grounded, step/touch, and bonded
  • Examine the distribution system as it pertains to grounding and understand resistance measurements, ground grids, and more
  • Grasp how electricity and grounding affects humans and animals and learn the threshold of fatality and perception
  • Define stray voltage and its mitigation techniques
  • Review stray and contact voltage scenarios (i.e., swimming pools, farms, fences, etc.)

Online Delivery

We will be using Microsoft Teams to facilitate your participation in the upcoming event. You do not need to have an existing Teams account in order to participate in the broadcast – the course will play in your browser and you will have the option of using a microphone to speak with the room and ask questions, or type any questions in via the chat window and our on-site representative will relay your question to the instructor.

  • You will receive a meeting invitation will include a link to join the meeting.
  • Separate meeting invitations will be sent for the morning and afternoon sessions of the course.
    • You will need to join the appropriate meeting at the appropriate time. 
  • If you are using a microphone, please ensure that it is muted until such time as you need to ask a question.
  • The remote meeting connection will be open approximately 30 minutes before the start of the course. We encourage you to connect as early as possible in case you experience any unforeseen problems.


Please Note: This event is being conducted entirely online. All attendees will connect and attend from their computer, one connection per purchase. For details please see our FAQ

If you are unable to attend at the scheduled date and time, we make recordings available to all registrants for three business days after the event
