This book was released on 2013-09 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1891 edition. Excerpt: ...cable-testing are scarcely applicable to every-day work, but should always be applied when testing cables at a factory for acceptance or rejection, as the various points enumerated above throw considerable light on the specific quality of the dielectric and its prospective durability. It is not to be imagined that an relaxation of careful methods is advocated in every-daj work, but it is not generally necessary in making periodical tests to take reversals or to take more than one minute's reading with the zinc current on each wire, except in the case of new cables or when a fault is suspected. CHAPTER XI. Test for Insulation.--(Continued.) To return to our specific example of the test for insulation resistance. The behavior of the spot should be carefully watched, and at the end of one minute from the time of turning on the current the exact deflection should be noted. This deflection serves for working out the insulation resistance by comparison with the galvanometer constant; the figures for insulation resistance are generally stated to be "after one minute's electrification." We will assume that the cable being tested is 2,640 feet long and that the deflection after one minute is 60 divisions on the scale. The constant of the galvanometer being 30,000, the absolute insulation resistance of the cable is-3 W9 = 500 megohms. As cables vary in length it is obviously useless, for purposes of comparison, to know the insulation resistance of a cable without also knowing its length, and even so it is not convenient to have to refer to two separate quantities; therefore it is usual to speak of the resistance per unit of length, and the insulation resistance per mile is the figure by which we can best judge of the actual condition of a...
Download or read book Electrical Connectors written by San Kyeong and published by John Wiley & Sons. This book was released on 2020-12-29 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Discover the foundations and nuances of electrical connectors in this comprehensive and insightful resource Electrical Connectors: Design, Manufacture, Test, and Selection delivers a comprehensive discussion of electrical connectors, from the components and materials that comprise them to their classifications and underwater, power, and high-speed signal applications. Accomplished engineer and author Michael G. Pecht offers readers a thorough explanation of the key performance and reliability concerns and trade-offs involved in electrical connector selection. Readers, both at introductory and advanced levels, will discover the latest industry standards for performance, reliability, and safety assurance. The book discusses everything a student or practicing engineer might require to design, manufacture, or select a connector for any targeted application. The science of contact physics, contact finishes, housing materials, and the full connector assembly process are all discussed at length, as are test methods, performance, and guidelines for various applications. Electrical Connectors covers a wide variety of other relevant and current topics, like: A comprehensive description of all electrical connectors, including their materials, components, applications, and classifications A discussion of the design and manufacture of all parts of a connector Application-specific criteria for contact resistance, signal quality, and temperature rise An examination of key suppliers, materials used, and the different types of data provided A presentation of guidelines for end-users involved in connector selection and design Perfect for connector manufacturers who select, design, and assemble connectors for their products or the end users who concern themselves with operational reliability of the system in which they’re installed, Electrical Connectors also belongs on the bookshelves of students learning the basics of electrical contacts and those who seek a general reference with best-practice advice on how to choose and test connectors for targeted applications.
