  • Operating transformers by temperature

    Publication Year: 1930, Page(s):3 - 6
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1004 KB)

    This paper discusses a proposal, sponsored by the Transformer Subcommittee of the Committee on Electrical Machinery, which is intended to serve as a guide in operating transformers by temperature rather than in accordance with their nameplate ratings. There is a real difference between “rating standards” and “recommendations for operation;” one simply specifies the meas... View full abstract»

  • Quiet induction motors

    Publication Year: 1930, Page(s):7 - 11
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1162 KB)

    Magnetic noise in induction motors is caused by the vibration of magnetic parts produced by the varying forces associated with the changing flux density in the adjacent air parts of the magnetic circuit. Torsional vibration of the motor is caused by unbalanced windings or applied voltages. Vibration of the rotor simulating a mechanically unbalanced rotor is caused by two fields differing by two po...

    The long distance telephone office serves to provide a concentration point for intercity telephone communication from a group of local exchanges, and its size mil depend largely upon the number of stations served by the local offices. The Chicago toll office, which serves 1,200,000 stations, recently has been replaced largely with new equipment. This equipment, together with correlated improvement... View full abstract»

  • Abridgment of the general circle diagram of electrical machinery

    Publication Year: 1930, Page(s):16 - 18
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (699 KB)

    The well-known circle diagram of a transmission network is applied to electrical machinery, giving circle diagrams of alternators, synchronous motors, synchronous condensers, and transformers. These diagrams give a graphical representation of the machine performance under all possible conditions. Such quantities as power loss, lower input, power output, field current., etc., for any operating cond... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (924 KB)

    A proposition to introduce a change in the units of the magnetic circuit was made at the meeting of the International Electrotechnical Commission, (I. E. C.) in Bellagio, September 1927. The proposition was referred to an international subcommittee for consideration and report, by the Advisory I. E. C. Committee on Nomenclature. The subcommittee has recently reported, recommending that the matter ... View full abstract»

  • Abridgment of dissipation of heat by radiation

    Publication Year: 1930, Page(s):22 - 24
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (641 KB)

    Heat dissipation is an ever-present factor affecting the design and operation of many kinds of electrical equipment. Usually, the problem is to get rid of heat due to losses. Sometimes the problem is how to conserve heat. Radiation, or convection, or conduction, or combinations of these, enter into all cases. Engineering literature as a rule presents conduction and convection in sound terms but in... View full abstract»

  • Abridgment of effects of electric shock

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1217 KB)

    This paper describes an investigation of the effects of electric shock on the central nervous system. A total of 286 rats was employed in the investigation. These were shocked at 110, 220, 500, and 1000 volts on both alternating- and continuous-current circuits for varying lengths of time. In each series the duration of the shock was increased until it was found impossible to resuscitate the rats.... View full abstract»

  • Abridgment of polyphase induction motors: A labor saving method of calculating performance from previously determined constants

    Publication Year: 1930, Page(s):29 - 33
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1022 KB)

    This paper presents a method of calculating polyphase induction motor performance which eliminates a large amount of detail work without making use of approximations which sacrifice accuracy. In any rigorous system for calculating induction motor performance, the determination of the relation between input and current values makes the greater part of the work. By the procedure here presented, the ... View full abstract»

    Theory and experimental data are given on the properties of discharges confined to small holes, such as the pores of a naturally porous material. The characteristics of these discharges are such that they are well suited for utilization in a valve type lightning arrester. View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2231 KB)

    This paper is the fifth of a series which the authors' have presented on the subject of synchronous machines. Part I was an extension of the fundamental theory: Part II, a treatment of torque-angle characteristics under steady-stale conditions; Part III, a study of torque-angle characteristics under transient conditions; and Part IV, an analysis of single-phase short-circuits. In the present paper... View full abstract»

  • Shaded lighting

    Too much cannot be said in favor of shaded lighting. Comparing shaded light with the bare lamp glare there is everything in favor of the shaded fixture. Soft light is always desirable. Its possibilities for decoration and its soothing effect on its surrounding contrast sharply against the undressed balls of flame which blind the eye and fray the nerves. View full abstract»

  • Abridgment of tap changing under load for voltage and phase-angle control

    Publication Year: 1930, Page(s):42 - 46
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1749 KB)

    One of the most important and sometimes most involved, problems brought about by the many interconnections of electrical systems, is a means of accurate and flexible regulation of power flow. The adjustment of voltage and the control of wattless current by means of tap-changing-under-load equipment has become quite extensive. The regulation of power flow by means of phase-angle control has been pu... View full abstract»

    Certain theories of the breakdown of gases are reviewed. Their limitations or correctness in the light of recent data on the breakdown of large gaps with surge voltages are considered. The work of various investigators on the time lag of breakdown also is discussed briefly. It is shown that comparisons are made difficult and that large discrepancies, particularly at the shorter time lags, may resu... View full abstract»

    The successful operation of an air transportation system depends in no small degree on the communication facilities at its command. Rapid and dependable communication between transport planes in flight and the ground is essential. Two-way radio telephony provides this necessary plane-to-ground contact. The design of a radio telephone system for this service requires quantitative knowledge of the t... View full abstract»
