Overview
To meet the Ohio Board's intent that online courses be "paced" by the provider, a timer will be used to record your study time. You will be unable to access the quiz until the required study time of 150 minutes has been met.

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.
