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.
Specific Knowledge or Skill Obtained
This course teaches the following specific knowledge and skills:
- The issues affecting substation grounding
- How to make soil resistivity measurements
- Touch and step potentials
- The limits of acceptable body currents
- How to design a substation grounding system
- How to calculate mesh voltages
- The impacts of corrosion on grounding systems
- How to make measurements of potential corrosive currents
- 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.
