This 4-hour course is the tenth in a series of courses on the design of electrical substations. The courses do not necessarily have to be taken in order and, for the most part, are stand-alone courses.
This course covers the design of the ground grid and discusses methods to protect the ground grid from corrosion.
Learning Objectives
Upon completion of this course, participants will be able to:
- Explain the issues that affect substation grounding.
- Perform soil resistivity measurements.
- Describe touch and step potentials.
- Identify the limits of acceptable body currents.
- Design a substation grounding system.
- Calculate mesh voltages.
- Explain the impact of corrosion on grounding systems.
- Perform measurements of potential corrosive currents.
- Identify the DC potentials of various metals.
Certificate of Completion
You will be able to immediately print a certificate of completion after passing a multiple-choice quiz consisting of 25 questions. PDH credits are not awarded until the course is completed and quiz is passed.
