IEEE Std 493 -2007 (Revision of IEEE Std 493-1997). IEEE Recommended Practice for the Design of Reliable Industrial and Commercial Power Systems. Gold Book

Institute of Electrical and Electronics Engineers, Inc, 2007— 383 p.
The objective of this recommended practice is to present the fundamentals of reliability analysis applied to the planning and design of industrial and commercial electric power distribution systems. The intended audience for this material is primarily consulting engineers and plant engineers, and technicians. The design of reliable industrial and commercial power distribution systems is important because of the high cost associated with power outages. It is necessary to consider the cost of power outages when making design decisions for new and existing power distribution systems as well as to have the ability to make quantitative “cost-versus-reliability” trade-off studies. The lack of credible data concerning equipment reliability and the cost of power outages has hindered engineers in making such studies. This revision of IEEE Std 493 overcomes these obstacles by providing extensive mechanical and electrical equipment reliability data; complete U.S. Army Corp of Engineers Power Reliability Enhancement Program (PREP) database, recent cost of power outage data, data collection procedures for maintenance and equipment failures, 7×24 continuous power analysis, and voltage sag analysis are presented. Detailed examples of reliability analysis of various industrial distribution system operating configurations are presented. The authors of this book have attempted to provide sufficient information so that reliability analyses can be performed on industrial and commercial power systems without requiring cross-references to other texts.
