    The paper describes recent developments in design of large hydroelectric generators. New features of mechanical construction made possible by fabricated designs are particularly emphasized and illustrations of some recent machines given. The 77,500-kv-a. generators for the Dneprostroy Project in Russia, (which will be the world's largest hydroelectric generators) are described. In conclusion, some... View full abstract»

    A review is given of the development of self-propelled railway vehicles which utilize electrical transmission, paying particular attention to the ways and means of regulating the torque demand on the internal combustion engine which serves as the source of power, and the supply of power to the auxiliaries. Two general designs are discussed and classified as “differential field controlȁ... View full abstract»

    Corona loss measurements were made on seven different conductor specimens. The losses were measured directly on a three-phase line 700 ft. long by means of three single-phase high-voltage wattmeters. The object of the test was to obtain data for the choice of conductor to be used on a 220-kv. 60-cycle line. The results show the effect of weathering conductors, the comparison of conductors of two d... View full abstract»

    Publication Year: 1930 , Page(s): 992 - 995
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (933 KB)  

    Experience has shown that the forces on turbine generator armature windings during short-circuit conditions are large, and that if adequate consideration is not given to the design of the coil bracing and support, windings may be seriously damaged. In this paper the forces are calculated for a particular case by the use of images, the change of flux interlinkages, and by the ∫ H2... View full abstract»

  • Forecasting seasonal precipitation in California: Its relation to electric power production

    Publication Year: 1930 , Page(s): 996 - 1001
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (1346 KB)  

    From an analysis of precipitation in significant districts of California, it is possible to deduce cycles or recurrences of from 2 to 3 years, from 5 to 6 years, and from 20 to 26 years, these being superimposed upon a longer or secular period of from 50 to 60 years. In this manner an estimate can be made of the rainfall to be expected over a relatively long period — as for the next 10 year... View full abstract»

  • Abridgment of damper windings for hydroelectric generators

    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (892 KB)  

    The severity of unsymmetrical system faults is affected by the negative sequence impedance of the connected machines. These impedances in turn depend largely upon the character of damper windings. The paper discusses the effect of amortisseur or damper windings upon both the real and reactive components of the negative sequence impedance. Machines without damper windings possess the highest negati... View full abstract»

    The past three years have seen a great increase of activity in the field of a-c. electrification of steam railroads, and consequently much attention has been given to the design of the single-phase traction motors upon which the success of this type of electrification chiefly depends. The object of this paper is to describe the up-to-date motors which have been developed to meet the requirements o... View full abstract»

    The paper deals with the development of the design of the single-phase series motor and some of the main features in both electrical and mechanical proportions which determine the service capacity in the application of this type of motor to railway electrification. Intensive study and development begun in the early part of 1927 resulted in the production of a single-phase series motor with more th... View full abstract»

    This paper shows the conditions affecting the magnitude and rate of rise of recovery voltage at the terminals of an oil circuit breaker upon interruption of a short circuit; also explaining their effect in quantitative terms. The most common locations, and a rough idea of the magnitude of the capacitances affecting the rate of rise of recovery voltage for various types of short circuit, are indica... View full abstract»

    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (3998 KB)  

    THE development of arc welding apparatus to its present efficient form has been a gradual process of evolution. In the early days all that was thought necessary for arc welding was a source of power which would supply the proper amperage; the ordinary 110-volt line, transformer, or d-c. generator, were considered entirely adequate. These sources of power were used in connection with a resistance o... View full abstract»

    Under the above caption, the I.E.S. Transactions for October describes a new device called “breath relay,” which consists of special contacts mounted in a small tube with a mouthpiece like that of a telephone, and is so designed that it responds only to a puff of air. Speaking into it, shaking it, or striking it has no effect. View full abstract»
