Explores the complex topic of grounding, essential to any power system, not only to protect equipment but the public at large. An introductory module looks at why we ground, how abnormalities arise in power circuits, and how the human body tolerates electricity. We then examine typical grounding systems, grounding system components, and the design of ground grids.
Who should take it: Anyone who is new to power distribution and power systems engineering, or who needs to refresh their understanding of power distribution fundamentals.
Job Positions include: Field Technicians; Distribution Line Workers; Designers; Engineers; Utility Managers; Engineering Managers; System Engineers, Operations Managers; Safety Managers; Communication Line Workers; and Electric Utility Contractors.

Introduction to Grounding of Power Distribution Systems Course (GD1)
Why we do grounding, the sources of overvoltage in the distribution system, and the currents the human body can tolerate. We also touch on how software can assist with calculations.
Course Code: GD1
Runtime: 30 minutes
Analysis of Grounding Systems for Distribution Circuits Course (GD2)
The fundamentals of grounding systems: how fault current flows under different fault conditions, how to calculate fault current magnitude and how to design a ground grid to handle these currents. We review the selection of components and touch on ground grid maintenance.
Course Code: GD2
Prerequisite: Introduction to Grounding of Power Distribution Systems (GD1)
Runtime: 45 minutes
Grounding System Components and Designs Course (GD3)
The grounding of system components such as substations, transformers and poles. We discuss special considerations and hazards and ground fault protection, then wrap up with a couple of case studies.
