Overview
This course is specifically designed for Ohio-licensed engineers to qualify as a "timed and monitored" online course. The course contains an automatic timer that prevents the user from accessing the quiz and earning a certificate of completion until the minimum amount of study time has been met. This achieves the Ohio Board's intent that an online course should be "paced" by the provider. For more information, please see the Ohio state requirements. This course may also be accepted in other states (see the "Board Acceptance" tab above). However, if you are not licensed in Ohio, it is suggested that you purchase the self-paced version of the course.

In Power System Neutral Grounding Fundamentals , you'll learn ...

  • Fundamental considerations for any form of grounding
  • Hazards of repetitive restriking
  • Basic theory of arcing ground faults
  • Definition of ‘effective grounding’

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.
