    Retiring President Osborne urges immediate planning to meet postwar engineering problems. The effective solution of these problems will require co-ordination with community and other planning. One problem of major importance is the greater unification of the engineering profession. View full abstract»

    This article is the concluding portion of the fifth lecture in the series on ultrashort waves sponsored by the basic science group of the AIEE New York Section. In the design of radiators or antennas for ultrashort waves a complete solution of Maxwell's field equations usually is not practicable, and engineering approximations are resorted to. The first installment (July issue) presented a method ... View full abstract»

    “In the interval since Tesla did his really great creative work his name has been associated with so many projects of questionable scientific quality that I imagine they may have raised doubts in the minds of many as to his real achievements” (Doctor Frank B. Jewett in a letter dated January 1943). The Edison Medal (1916) was awarded by the AIEE to Tesla “for his early origina... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1341 KB)

    FARADAY'S principle of electromagnetic induction discovered in 1831 after some 40 years of incubation resulted in practical forms of dynamo machines. Electricity from mechanical power (instead of costly batteries) stimulated invention of apparatus and the development of various methods or “systems” for distributing and utilizing the electric current. The evolution of “systems&... View full abstract»

    DURING the early part of the last decade of the 19th century the attention of the whole scientific world was challenged by Nikola Tesla's public demonstrations of the effects of high-frequency alternating currents. It was then very early in the commercial age of electricity. The incandescent light had not yet become commonplace, electric traction was just being introduced, and the controversy over...

    ANUMBER of papers have been written which discuss individual pilot-wire relaying schemes. A recent paper presented by the relay subcommittee of the committee on protective devices1 analyzed the pilot-wire circuit used in these relaying schemes. The present paper is a discussion of pilot-wire systems on a large metropolitan system where they have been in successful use for many years. Th... View full abstract»

    The demand for public transportation is increasing rapidly under present conditions of accelerated industrial activity. Adequate maintenance of electrical apparatus on rolling stock is essential to avoid impairment to the war effort. Measures which will assist to retain generators, motors, and control in service practically 100 per cent of the time are proper operation, effective inspection, preve... View full abstract»

    The preceding paper of this series1 presented the theory and principles of operation of a new type of a-c motor and its control circuit. This system of speed control has the advantage of being economical from the standpoints of initial cost, efficiency of operation, and ability to correct power factor. However, these advantages are not realized unless the machine is suitably designed an... View full abstract»

    A core-type power-transformer design with shielded high-voltage winding and graded insulation has been developed for application in the higher-voltage classifications, and up to the present time more than one-quarter million kilovolt-ampere capacity of this kind of transformer has been manufactured and placed in service. The design employs a new form of construction for high-voltage power transfor... View full abstract»

    For three years surveys have been made of the operation of small single-pole automatic reclosing oil circuit breakers (also called “oil circuit reclosers” and “service restorers”1) on rural electric distribution systems financed by the Rural Electrification Administration. Results of these surveys indicate that the ratio of lockouts to operations is less than... View full abstract»

    A capacitance bridge for the calibration of instrument potential transformers up to 300 kv is presented in this paper. This bridge provides measurements which are correct within 0.1 per cent on ratio and 3 minutes on phase angle. There are within the bridge arrangements for testing its accuracy as determined by the stability of its component arms. It is particularly desirable to have this means of... View full abstract»

    WHEN carrier current was first applied to protective relaying of the directional type, it consisted of a simple telegraph channel. Subsequent developments have expanded the capabilities to the extent that each carrier channel for pilot relaying now may provide one or more of the following additional services: View full abstract»
