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.
