Foreword 

This guide is the second in a series of documents on neutral grounding in electric utility systems. Part II covers the considerations and practices relating to the grounding of synchronous generator systems.

Emphasis in this guide is to be directed toward the grounding of synchronous generator systems in electric utility systems. Generator grounding practices used in industrial systems are covered in other guides and standards.

Scope

This section summarizes the general considerations in grounding synchronous generator systems and discusses the factors to be considered in the selection of a grounding class and the application of grounding methods. The guidelines apply to both the large and small generators found in electric utility systems.

It should be borne in mind by the user that this report is intended solely as a guide. Statements are necessarily of a general nature and, therefore, do not take into account the requirements of special situations that can differ considerably from those discussed.
