C62.92.1-2016

IEEE Guide for the Application of Neutral Grounding in Electrical Utility Systems--Part I: Introduction

The application of neutral grounding to three-phase electrical utility systems is described in this guide. It is Part 1 of the IEEE C62.92 series of guides for neutral grounding. This guide presents basic considerations of the selection of neutral grounding parameters that will provide for the control of overvoltage and ground-fault current on all parts of three-phase electrical utility systems rated greater than 1000 V.

C62.92.2-2017

IEEE Guide for the Application of Neutral Grounding in Electrical Utility Systems, Part II--Synchronous Generator Systems

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 of grounding terms used in this the guide can be found in IEEE Std C62.92.1(TM)-2000.

C62.92.3-2012

IEEE Guide for the Application of Neutral Grounding in Electrical Utility Systems, Part III -Generator Auxiliary Systems

Basic factors and general considerations in selecting the class and means of neutral grounding for electrical generating plant auxiliary power systems are given in this guide. Apparatus to be used to achieve the desired grounding are suggested, and methods to specify the grounding devices are given. Sensitivity and selectivity of equipment ground-fault protection as affected by selection of the neutral grounding device are discussed, with examples.

C62.92.4-2014

IEEE Guide for the Application of Neutral Grounding in Electrical Utility Systems--Part IV: Distribution

The neutral grounding of single- and three-phase ac electric-utility primary distribution systems with nominal voltages in the range of 2.4 kV u2013 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, and ground relaying are addressed. Also considered is the use of grounding transformers, grounding of high-voltage neutral of wye-delta distribution transformers, and interconnection of primary and secondary neutrals of distribution transformers.

C62.92-1987

IEEE Guide for the Application of Neutral Grounding in Electrical Utility Systems, Part 1 - Introduction

Some basic considerations for the selection of neutral grounding parameters that will provide for the control of ground-fault current and overvoltage on all portions of three-phase electrical utility systems are presented. These considerations apply specifically to electric utility systems and do not recognize the neutral grounding requirements for dispersed storage and generation. They are intended to serve as an introduction to a series of standards on neutral grounding in electrical utility systems.

C62.92.2-1989

IEEE Guide for the Application of Neutral Grounding in Electrical Utility Systems, Part II - Grounding of Synchronous Generator Systems

General considerations for grounding synchronous generator systems are summarized, focusing on the objectives of generator grounding. The factors to be considered in the selection of a grounding class and the application of grounding methods are discussed. Four generator grounding types are considered: unit-connected generation systems, common-bus generators without feeders, generators with feeders directly connected at generated voltage, and three-phase, 4-wire connected generators.
