Applications to three-phase electrical utility systems are described in this Part VI of the IEEE C62.92(TM) series. Definitions and considerations related to system grounding where the dominant sources of system energization are current-regulated or power-regulated power conversion devices are provided.
The basic factors and general considerations in selecting the class and means of neutral grounding for synchronous generator systems connected to electrical utility systems are provided in this guide. It also provides the suggested methods and apparatus to be used to achieve the desired grounding. These guidelines apply to both large and small generators found in electrical utility systems. Definitions...
This guide is the introduction to the C62.92 series of five IEEE guides on neutral grounding in three-phase electrical utility systems.It provides system grounding definitions and considerations that are general to all types of electrical utility systems.
The neutral grounding of single- and three-phase ac electric-utility primary distribution systems with nominal voltages in the range of 2.4 kV 34.5 kV is addressed. Classes of distribution-systems grounding are defined. Basic considerations in distribution-system grounding concerning economics, control of temporary overvoltages, control of ground-fault currents, andground relaying are addressed. Also...

Grounding practices that have generally been accepted by the electric utility industry as contributing to effective grounding systems for personnel safety and equipment protection in generating stations are identified. A guide for the design of generating station grounding systems and for grounding practices applied to generating station indoor and outdoor structures and equipment, including the interconnection...
Basic factors and general considerations in selecting the class and means of neutral grounding for a particular ac transmission or sub transmission system are covered. An apparatus to be used to achieve the desired grounding is suggested, and methods for specifying the grounding devices are given. Transformer tertiary systems, equipment-neutral grounding, and the effects of series compensation on...
