Book Synopsis A Practical Guide to Short-circuit Current Calculations by : Conrad St. Pierre
Download or read book A Practical Guide to Short-circuit Current Calculations written by Conrad St. Pierre and published by . This book was released on 2001 with total page 557 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Practical Guide to Short-Circuit Calculations put just about everything needed for short-circuit calculations in one 520 page reference. Descriptions and sample calculations are provided for ANSI and IEC methods. Once the calculations are done, comparing these results with the equipment rating is explained. While the book does cover some of the fundamental of short circuits, it main purpose is to get correct answers quickly for the application of equipment. The appendix has over 200 pages of data on cables, busway, machines, and transformers. Cable impedances up to 34.5 kV are given for both AWG and mm2 sizes. "I did a quick review of the book last weekend and was impressed by both the content and organization. There are many handy hints and examples and a comprehensive listing of equipment ratings. This is the first time I have seen it all in one nice text and consider this a 'must have' reference for any serious power system engineer." (FJA, PE). "The cover's printing and material are quality stuff. Just thumbed through a number of pages and it reads very easy, the print is right, the layout right, the graphics are real good." (JDJ, PE)
Book Synopsis Overcurrent Protection NEC Article 240 and Beyond by : Gregory P. Bierals
Download or read book Overcurrent Protection NEC Article 240 and Beyond written by Gregory P. Bierals and published by CRC Press. This book was released on 2021-12-23 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: An overcurrent is caused by a short-circuit, ground-fault, or an overload. A short-circuit may be hundreds or even thousands of times above the normal operating current. This type of fault may be an arcing fault between ungrounded conductors or between an ungrounded conductor and a grounded (usually, a neutral) conductor, a line-to-line arcing fault may produce a current of 74% of a 3-phase bolted fault. A line-to-neutral arcing fault will be somewhat less. A line-to-line bolted fault, the equivalent, of the conductors bolted together, may be up to 100% of the available short-circuit current. A line-to-neutral bolted fault may be in excess of 100% of the 3-phase bolted fault at the source, but considerably less downstream. A ground-fault, that is, the equivalent of a connection between an ungrounded conductor and the equipment grounding system, will produce a current that may be 38% or higher of the 3-phase bolted fault current. These types of faults are typically arcing faults which normally are intermittent in nature. That is, they strike and restrike over time and may produce a short-circuit fault due to insulation damage. Once again, a line-to-equipment ground fault near the source may produce a fault current of over 100% of the 3-phase bolted fault, but considerably less downstream. An overload typically ranges from one to six times the normal current, and are normally caused by motor starting currents or transformer magnetizing currents. These conditions are of such short duration that the circuit components are not damaged. This book has a detailed analysis of these types of faults, along with explanations and examples of the various types of overcurrent protective devices to assure proper protection. This volume has extensive information on the application of overcurrent protection for conductors and equipment. The reader will be able to calculate fault currents as well as establishing the short-circuit withstand rating of conductor insulation and to determine the appropriate type of overcurrent devices based on circuit conditions. In addition, determining ground-fault currents for the purpose of selecting the proper size of equipment grounding conductors to establish an effective ground-fault current path is discussed in detail. Readership - Anyone involved with the design of overcurrent protection for electrical distribution systems from the system source to the electrical utilization equipment. The emphasis is placed on the design of the overcurrent protection for specific installations to assure proper protection for the circuit components regardless of the type of fault encountered.

Book excerpt: Switching in Electrical Transmission and Distribution Systems presents the issues and technological solutions associated with switching in power systems, from medium to ultra-high voltage. The book systematically discusses the electrical aspects of switching, details the way load and fault currents are interrupted, the impact of fault currents, and compares switching equipment in particular circuit-breakers. The authors also explain all examples of practical switching phenomena by examining real measurements from switching tests. Other highlights include: up to date commentary on new developments in transmission and distribution technology such as ultra-high voltage systems, vacuum switchgear for high-voltage, generator circuit-breakers, distributed generation, DC-interruption, aspects of cable systems, disconnector switching, very fast transients, and circuit-breaker reliability studies. Key features: Summarises the issues and technological solutions associated with the switching of currents in transmission and distribution systems. Introduces and explains recent developments such as vacuum switchgear for transmission systems, SF6 environmental consequences and alternatives, and circuit-breaker testing. Provides practical guidance on how to deal with unacceptable switching transients. Details the worldwide IEC (International Electrotechnical Commission) standards on switching equipment, illustrating current circuit-breaker applications. Features many figures and tables originating from full-power tests and established training courses, or from measurements in real networks. Focuses on practical and application issues relevant to practicing engineers. Essential reading for electrical engineers, utility engineers, power system application engineers, consultants and power systems asset managers, postgraduates and final year power system undergraduates.
