Electric Distribution Grounding & Stray Voltage
March 25-26, 2020 | New Orleans, LA

The electric distribution ground system is a complex network of various paths and accommodates the return current back to the substation. Ohm’s Law tells us that any current passing through an impedance creates a voltage. If we acknowledge that the ground path(s) is not a perfect a conductor, we know that stray voltage is inevitable.

This course 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.

Learning Outcomes 

  • Review the basic electrical formulas associated with grounding and stray voltage
  • Identify how transient events create hazards which may be dangerous to the public and utility personnel, as well as damage equipment
  • Review Section 9 of the National Electric Safety Code and learn acceptable grounding methods
  • Review the definitions of commonly used terms such as “effectively grounded” and “bonded”
  • Identify ground resistance measurement for both substations and the distribution system
  • Assess the effects of electricity on biological objects (animals and human beings)
  • Discuss the definition of stray voltage
  • Discuss stray voltage trouble shooting and mitigation techniques
  • Review various stray voltage scenarios
