Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Low-voltage metal-enclosed switchgear-which contains either stationary or drawout, manually or electrically operated low-voltage ac or dc power circuit breakers in individual grounded metal compartments, in three-pole, two-pole, or single-pole construction-is covered. Rated maximum voltage levels are 254 V, 508 V, or 635 V (ac) and 300/325 V, 800 V, 1000 V, 1200 V, 1600 V, or 3200 V (dc). The preferred continuous current ratings of the main bus in ac designs are 1600 A, 2000 A, 3000 A, 3200 A, 4000 A, or 5000 A. For dc designs, the preferred ratings are 1600 A, 2000 A, 2500 A, 3000 A, 4000 A, 5000 A, 6000 A, 8000 A, 10 000 A, or 12 000 A. The switchgear may also contain associated control, instruments, metering, protective, and regulating devices as necessary. The standard deals with service conditions, ratings, temperature limitations, and classification of insulating materials, insulation (dielectric) withstand voltage requirements, test procedures, and application.

Available in PDF, EPUB and Kindle. Book excerpt: This amendment addresses additional requirements of auxiliary power wiring and control wiring within dc switchgear of traction power substations with rated maximum voltage up to 3200 volts dc. It also provides control and power wiring methods for dc traction power switchgear intended to increase reliability of the operation of the equipment, improve protection, reduce maintenance cost and initial cost, and improve overall performance of the dc traction power switchgear.
