One of the most critical decisions faced by the designer of a power system is how the neutral of the system should be grounded.
This course presents the subject of neutral grounding in a very structured fashion. First, a simple equivalent circuit is developed for a generic power system, and then each of the options for neutral grounding is ‘tested’ in that equivalent circuit to identify and understand the characteristics of the grounding method. A detailed explanation is offered for each of the following options: Ungrounded neutral; Solidly grounded neutral; Low resistance grounded neutral; High resistance grounded neutral; Low inductance grounded neutral; High inductance (resonant) grounded neutral.
Learning Objectives
Upon completion of this course, participants will be able to:
- Explain fundamental considerations for any form of grounding.
- Describe the hazards of repetitive restriking.
- Explain basic theory of arcing ground faults.
- Define "effective grounding".
- Explain the impact of the grounding method on step- and reach-potentials.
- Design the criteria for high-resistance grounding.
- Describe the limitations of high-resistance grounding.
- Explain the impact of grounding on cable selection.
- Describe the ideal short-circuit stiffness based on total loading.
- Explain application limitations of reactance grounding.
- Describe special considerations for Peterson coil grounding.
- Distinguish between system neutral grounding and bonding.
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.
