"The definitive account of the crash of 1987, a cautionary tale of how the U.S. financial system nearly collapsed ... Monday, October 19, 1987, was by far the worst day in Wall Street history. The market fell 22.6 percent--almost twice as bad as the worst day of 1929--equal to a loss of nearly 5,000 points today. But Black Monday was more than just a one-day market crash; it was seven years in the making and threatened the entire U.S. financial system. Drawing on superlative archival research and dozens of original interviews, the award-winning financial journalist Diana B. Henriques weaves a tale of ignored warnings, market delusions, and destructive decisions, a drama that stretches from New York and Washington to Chicago and California. Among the central characters are pension fund managers, bank presidents, government regulators, exchange executives, and a pair of university professors whose bright idea for reducing risk backfires with devastating consequences. As the story hurtles toward a terrible reckoning, the players struggle to avoid a national panic, and unexpected heroes step in to avert total disaster. For thirty years, investors, bankers, and regulators have failed to heed the lessons of Black Monday. But with uncanny precision, all the key fault lines of the devastating crisis of 2008--breakneck automation, poorly understood financial products fueled by vast amounts of borrowed money, fragmented regulation, gigantic herdlike investors--were first exposed as hazards in 1987. A First-Class Catastrophe offers a new way of looking not only at the past but at our financial future as well."--Dust jacket.
Showing the relation of physics to circuit interruption technology, describes for engineers the switching phenomena, test procedures, and applications of modern, high-voltage circuit breakers, especially SF, gas-blast, and the vacuum types used in medium-voltage ranges. Applies the physical arc mode
This title discusses, in depth, the wide range of technologies that are involved in power circuit breaker design by analysing the theoretical and practical problems.
"A new text/workbook that covers low- and medium-voltage circuit breakers used in commercial, industrial, and utility applications and provides comprehensive information on circuit breaker construction, operation , troubleshooting, and maintenance."--Back cover.
Introduction to Business covers the scope and sequence of most introductory business courses. The book provides detailed explanations in the context of core themes such as customer satisfaction, ethics, entrepreneurship, global business, and managing change. Introduction to Business includes hundreds of current business examples from a range of industries and geographic locations, which feature a variety of individuals. The outcome is a balanced approach to the theory and application of business concepts, with attention to the knowledge and skills necessary for student success in this course and beyond. This is an adaptation of Introduction to Business by OpenStax. You can access the textbook as pdf for free at openstax.org.

Here-in one current, comprehensive source-is a wealth of both theoretical and practicalinformation on circuit interruption. Twenty-two authorities at the leading edge of researchand development provide a solid grasp of circuit breaker design and performance... and that's knowledge you can put to work immediately!arcuit Interruption surpasses other books in completeness and currency-includingcoverage of the sulfur hexafluoride puffer, the vacuum breaker, and the low-voltagemolded-case breakers, that are taking the place of many older types. In addition to thelatest theories and techniques, this major volume examines promising future trends.More than 400 clear illustrations help make the text easy to follow, and over 620 keyreferences point the way to the best places for continuing study.Today, the field of circuit interruption is so diverse that a thorough single source reallystands out. arcuit Interruption is that- source, the perfect reference for electrical, electronic,power, and design engineers; and researchers investigating circuit breaker design,interaction of breakers and power circuits, power transmission, power distribution,circuit interruption, electric contacts, and gaseous conduction. Moreover, this exceptionalbook serves as an excellent source for practicing power engineers as well as an invaluablesupplement to graduate-level engineering courses in circuit interruption, transmission,and distribution of power . . . and a supplement in professional seminars and society/association courses.
This newly revised and updated reference presents sensible approaches to the design, selection, and usage of high-voltage circuit breakers-highlighting compliance issues concerning new and aging equipment to the evolving standards set forth by the American National Standards Institute and the International Electrotechnical Commission. This edition features the latest advances in mechanical and dielectric design and application from a simplified qualitative perspective. High Voltage Circuit Breakers: Design and Applications features new material on contact resistance, insulating film coatings, and fretting; temperature at the point of contact; short-time heating of copper; erosion and electromagnetic forces on contacts; closing speed and circuit breaker requirements; "weld" break and contact bounce; factors influencing dielectric strength; air, SF6, vacuum, and solid insulation; and dielectric loss and partial discharges, and includes updated chapters on capacitance switching; switching series and shunt reactors; temporary overvoltages; and the benefits of condition monitoring.
