  • The effect of alternating current on the resistance and reactance of iron and steel wires

    Creator:
    Eckley, Winfield
    Abstract:
    During the past year the rapid increase in the cost of copper and aluminum has led operating companies to investigate the feasibility of using iron and steel conductors for transmission and distribution purposes where small blocks of power are to be served. This Thesis gives the results of tests on...

  • 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...

  • 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...

  • 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...

  • 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...

  • Arcing grounds in transmission lines and their resultant phenomena

    Creator:
    Oakes, Charles E.
    Abstract:
    In any electrical system no part is stronger than the weakest link. It is very important that the insulation of the transmission line be kept intact at all times. For this reason any improvement in the design or manufacture of insulators would be desirable. The object of this research was...

  • Indirect Illumination

    Creator:
    McMillan, Fred Orville and Smith, Hugh Isaac
    Abstract:
    The scope of this thesis consists primarily of an exposition upon the merits of indirect and. semi-indirect illumination. In deriving our conclusions, we have considered two sources of information: firstly, that of test data from a number of indirect and direct installations, and. secondly, the opinion of men familiar with...

  • The Test of an Induction Motor Generator Set

    Creator:
    Plankinton, John C. and Gianella, Vincent Paul
    Abstract:
    This thesis comprises a series of tests run on a compound direct current generator and an induction motor; separately and combined as a set, with sheets of data; characteristic and efficiency curves and deduction drawn therefrom relative to the two machines.

    Creator:
    Powell, Joel William and Booth, Latimer Hobart
    Abstract:
    The marked movement of utilizing Oregon's water power in the service of generating electric current, has been promoted by the economics in transmission of electricity to distances both great and small; by the harnessing of industrial implements to electric power; and by the advancement and extension of interurban railways. It...
