  • Power plant design

    Creator:
    Propst, Horace Minor and Sorenson, Edgar Adolf
    Abstract:
    During the last five years the demand for electrical energy in the state of Oregon,and throughout the entire country,has increased to such an extent that electrical generating stations have become an important factor in the economic development of the common wealth. Uonsidering the great need for cheap power, which is...

  • Rectifiers

    Creator:
    Harris, Lee Marion and Du Moulin, Walter Wilbur
    Abstract:
    "There are at present four common methods of con verting the alternating current into direct current. These are in order of use, the motor generator set, the rotary converter, mercury vapor rectifier and the Murphy rectifier. A short description of these and connections for the last two will be given."--p.2

  • Performance Test of an Induction Motor

    Creator:
    Bowman, Harry David and Cady, Harry Palmer
    Abstract:
    The induction motor in its electromagnetic features is essentially a transformer, while in its general behavior it is analogous to the continuous-current shunt wound motor. In a transformer the primary and secondary members are both stationary and electrical energy is transformed from one pressure to another by the ratio of...

  • High Tension Transformer

    Creator:
    Olsen, Bernhard, 1836-1922 and McLean, Howard Elmer
    Abstract:
    In view of the fact that the college authorities have purchased a set of wireless apparatus, it was thought best to design and construct a transformer of suitable size for transforming the power to be used by this set of instruments. The power required for such a set is approximately...

  • Design of a Standard Speed, Revolving Field Type, Three Phase Alternator

    Creator:
    Williams, Floyd J. (Floyd James), 1920- and Rawson, Roy Eugene
    Abstract:
    The designing of electrical machinery is fully as essential to the thorough understanding of power equipment and apparatus, as is the taking of a laboratory testing course. One learns the relationship of the different parts, the methods of computing their dimensions, and the predetermination of outputs, efficiencies, etc. and thus...

    Creator:
    Carnegie, John Darwin and Borden, Roy
    Abstract:
    By reason of the fact that a thesis along the line of one's course or about some subject with which he is supposed to be familiar is required of every Senior electrical by the electrical department before his graduation, the following description of the design and construction of a 10...

  • Design, Construction, Operation and Uses of a 110,000 Volt Testing Transformer

    Creator:
    McLagan, Wayne Carl and Vines, John Oscar
    Abstract:
    Samples of insulating materials used in the construction of electrical machinery and apparatus are tested for dielectric strength before such are accepted for use. This is done by applying to the sample a high voltage until it is pierced through by the electric spark. This is a parallel case to...

  • The Testing of an Alternator

    Creator:
    Fleser, Russell Harrison and Billings, Everett Monroe
    Abstract:
    "Before a company which manufactures electrical machines allow them to leave the factory, each must undergo certain tests to make sure that there are no faults of design or workmanship and also ofttimes that they meet the specifications of the buyer. Four important tests are made, e.g. (1) no load...

    Creator:
    Stutz, Lester Eugene and Pernot, Fred Eugene
    Abstract:
    Throughout the year the regular design work of the class room proved so profitable that it was thought that there was no subject which could be selected for thesis purposes of greater benefit,or which offered as great a latitude in the working out of the various problems, than the one...
