Methods of Grounding In Power Systems

Methods of Grounding In Power Systems

The Methods of Grounding In Power Systems training course provides a practical understanding of system and equipment grounding.

You can access the live online training through our web-based platform from your own computer. You can see and hear the instructor and see his screen live.

You can interact and ask questions. The cost of the training also includes 7 days of email mentoring with the instructor.

Actual case studies and in-class exercises provide knowledge needed for solving grounding problems, designing new systems or maintaining existing facilities. Power systems grounding problems cause unexplained system outages. Highly qualified Siemens Westinghouse instructors can provide you with knowledge and experience to recognize, evaluate and verify grounding system elements.


Course Objectives:

  • 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
  • Outline NEC Requirements
  • Summarize Computer and Instrumentation Grounding
  • Explain Ground Grid Resistance

WHO should attend

The Methods of Grounding In Power Systems training course is suggested for graduate engineers or personnel with equivalent work experience in electrical power systems. Consultants, application engineers, design engineers and electrical engineers from large industrial plants or municipal distribution systems will find this course very beneficial. Attendance at the Siemens Westinghouse Industrial Power Systems Analysis Seminar or equivalent is strongly recommended as a prerequisite.
