This course can be scheduled at your convenience, to request this course please click here


The Power Systems Grounding training course provides a theoretical & practical understanding of system and equipment grounding. Actual case studies and in-class exercises provide knowledge needed for solving grounding examples and case studies problems, designing new systems or maintaining existing facilities. Power systems grounding problems cause unexplained system outages.

This course covers concepts of system grounding and equipment grounding and safety grounding of equipment in substations, as well as the installation, testing, and maintenance of grounding. The course also introduces the IEEE 80 method of safety grounding design, applicable standards and grounding codes, and possible electrical system anomalies. Concepts will be illustrated through case studies and hands-on exercises under instructor guidance.



Upon completion of this course, the participant shall be able to;

  • Explain the Reasons for Grounding, Shock Hazards, System Ground Versus Equipment Grounds
  • Describe the Basics of System Grounding
  • Describe Typical Ground Fault Schemes and Switchgear Performance Testing
  • Explain Symmetrical and Fault Calculations
  • Summarize Computer and Instrumentation Grounding
  • Explain Ground Grid Resistance
