Full Description
Purpose
The purpose of these guides are to present 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 electric utility systems. It also provides 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 and summarize the general considerations in grounding of generating station auxiliary power systems, the factors to be considered in selecting between the appropriate grounding classes, and specifying equipment ratings. Discussed are the term distribution includes the substation providing power to distribution feeders, the distribution feeders, and the distribution transformers providing service at utilization voltages. It also provides the basic factors and general considerations in selecting the class and means of neutral grounding for a particular ac transmission or sub-transmission system, and the suggested method and apparatus to be used to achieve the desired grounding.
Abstract
- Active.The purpose of these guides are to present 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 electric utility systems. The factors to be considered in the selection of a grounding class and the application of grounding methods are discussed. General considerations in selecting the class and means of neutral grounding for electrical generating plant auxiliary power systems are given in these guides. 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. 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. This bundle includes: IEEE Std C62.92.1-2016, IEEE Std C62.92.2-2017, IEEE Std C62.92.3-2012, IEEE Std C62.92.4-2014, IEEE Std C62.92.5-2009, and IEEE Std C62.92.6-2017
