Switchgear and Control Handbook [antikvár]

Preface This Handbook was written to provide practical engineering data for assisting engineers in selecting and specifying switchgear and control. It also provides installation and maintenance information for plant and maintenance engineers and for technicians and electricians who install and care for this equipment. Through this Handbook, eminently qualified engineers give the reader the benefit of their many years of practical experience. The thirty-four contributors have become widely known through their published books, technical articles, engineering papers, and through committee activities in their engineering societies. Sections 1, 2, and 3 cover fundamental information on switchgear, its classifications and arrangements, control standards, general purpose motor starters, and control circuit devices used with both switch-gear and control. System considerations affecting switchgear and control selection are given in Sections 4 through 7. Sections 8 and 9 cover installation and service requirements, including earthquake considerations, that must be understood when specifying switchgear and control. An important background on load and motor characteristics affecting control selection is given in Sections 10 and 11. Sections 12 through 15 provide an excellent guide to the coordination of system protection and instrumentation. Plant engineers and engineering consultants are given information in Sections 16 through 21 for planning and specifying distribution and utilization systems which may include switchgear, control, substation, bus duct, distribution panelboards and switchboards. Process design and application engineers are provided a wide variety of control system information in Sections 22 through 29, enabling them to specify controls from standardized polyphase motor
