29、ystems in Industrial and Commercial Facilities. IEEE 3000 Standards CollectionTMThis recommended practice was developed by the Technical Books Coordinating Committee of the Industrial and Commercial Power Systems Department of the Industry Applications Society as part of a project to repackage the p
30、opular IEEE Color Books. The goal of this project is to speed up the revision process, eliminate duplicate material, and facilitate use of modern publishing and distribution technologies. When this project is completed, the technical material in the thirteen IEEE Color Books will be included in a se
31、ries of new standardsthe most significant of which will be a new standard, IEEE Std 3000TM, IEEE Recommended Practice for the Engineering of Industrial and Commercial Power Systems. The new standard will cover the fundamentals of planning, design, analysis, construction, installation, startup, opera
32、tion, and maintenance of electrical systems in industrial and commercial facilities. Approximately 60 additional dot standards, organized into the following categories, will provide in-depth treatment of many of the topics introduced by IEEE Std 3000TM: Power Systems Design (3001 series) Power Syste
33、ms Analysis (3002 series) Power Systems Grounding (3003 series) Protection and Coordination (3004 series) Emergency, Standby Power, and Energy Management Systems (3005 series) Power Systems Reliability (3006 series) Power Systems Maintenance, Operations, and Safety (3007 series) In many cases, the m
34、aterial in a dot standard comes from a particular chapter of a particular IEEE Color Book. In other cases, material from several IEEE Color Books has been combined into a new dot standard. This recommended practice is an update and expansion of the material in Chapter 8 of IEEE Std 493TM(IEEE Gold B
35、ookTM). IEEE Std 3006.7TMThe explosive growth of computer technology has literally changed the way business is conducted. Cell phones, text messaging, and e-mail have become the norm and the Internet provides a communication medium not previously available. Stock trading and banking, along with an i
36、ncredible diversity of retail sales, occur daily via the Internet. With the broad expansion of computer technology comes the necessity of providing an infrastructure capable of supporting it. The ITIC susceptibility curve, from IEEE Std 1100TM-2005 (IEEE Emerald BookTM) shows that electronic equipme
37、nt can be disrupted by a momentary sag of 20 ms. Two voltage immunity standards currently available have it as 10-ms minimum ride-through time; EN55024 from Special International Committee on Radio Interference (CISPR) and International Electrotechnical Commission (IEC) 61000-6-1, 2005-03. Momentary
38、 interruptions of the electrical power can have huge financial consequences. Therefore, specialty equipment, such as uninterruptible power supplies Copyright 2013 IEEE. All rights reserved. ix (UPS), emergency generators, and automatic static transfer switches (STSs) are used to supplement utility p
39、ower. Initially, special facilities were designed for mainframe computers, used primarily for banking and finance, called data centers. As the use of computers broadened and support of the Internet became a significant market, along with divestiture of the telecommunications industry, the term 724 f
40、acility became common. This term is derived from the requirement that the facility operates 7 days a week, 24 hours per day. Copyright 2013 IEEE. All rights reserved. x Contents 1.
