  • Half-wave magnetic amplifier circuit input power

    Publication Year: 1957, Page(s): 186
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (452 KB)

    THE MECHANISM OF AMPLIFICATION of the self-saturating magnetic amplifier, in general, consists of its flux control of the magnetic core. In order to control the flux level in the core, the core loss must be supplied from the control circuit during the control half-cycle of the specific core. In order to demonstrate the correlation between the input power and the reset core loss in the case of the ... View full abstract»

  • Emissivity effects on stranded Aluminum conductors

    Publication Year: 1957, Page(s): 195
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (412 KB)

    AN APPARATUS for the measurement of total hemispherical emissivity of stranded conductor was recently developed. A measurement is made by suspending the specimen in the center of an evacuated chamber, heating the specimen, and taking a cooling curve. New stranded aluminum conductors have emissivity values of about 20 to 25% (per cent); old, weathered conductors may have emissivities of 90% or high... View full abstract»

    IN RECENT YEARS there has been a large increase in the number of communication, telemetering, pilot wire relay, and other control circuits required by power utilities in Canada. Service continuity on these circuits is of prime importance, and neutralizing transformers are required in many cases to maintain this continuity and to prevent damage to the circuits or terminal apparatus as the result of...

    Characteristics of Supermendur, a new vanadium-iron-cobalt alloy with exceptional magnetic properties, are discussed. Advantages include low coercive force, low hysteresis loss, high permeability, and high remanence. This material promises to be of value in telephone receiver diaphragms, miniaturization, high-temperature applications, and switching and memory devices. View full abstract»

    THE RAPID GROWTH in the utilization of electric energy and the importance of continuity of service has increased the application of protective relays. This magnifies the problems of space, which is already at a premium in many existing stations and an increasingly costly item in new stations. A critical examination indicated that considerable savings in space could be effected in many of the relay... View full abstract»

  • Field treatment in electric shock cases

    Electric shocks of the order of 0.1 ampere can throw the heart into a twitching state of ventricular fibrillation. Several amperes, on the other hand, simply contract the heart and paralyze the breathing which artificial respiration can relieve, Ventricular fibrillation, however, can be ended only by sending sufficient current through the heart by electrodes on the skin of the chest.

    The mountain sheep-pleasant valley project is located in the rugged, mountainous section of the Snake River, immediately downstream from the Idaho Power Company's Hell's Canyon site. The ultimate development will add 1,446 megawatts to the Northwest Power Pool which faces a possible shortage of power after 1960. The Pleasant Valley power plant (see Fig. 1) would have the third highest true-arch da... View full abstract»
