A Thesis Presented To The President And The Faculty Of Marquette University For The Degree Of Bachelor Of Science In Civil Engineering And Bachelor Of Science In Electrical Engineering, Anthony B. Czachurski, Benjamin D. Ratke, Joseph G. Casey, William H. Stephan

Bachelors’ Theses

In the work covered by this thesis it is desired to examine an undeveloped water power for the purpose of producing electrical energy as a commercial comodity. Experience has taught that it is best to ascertain first where the product will find its market, and to follow up a satisfactory showing at that end by determining the power capacity of the source, the feasibility of harnessing the same, and the cost of accomplishing this. This program would be adopted in any commercial enterprise to insure a reliable conclusion, and will be followed as closely as possible in the work covered …

Commutation, John Th. Mueller, Edward J. Blackwell

Bachelors’ Theses

The E.M.F. induced in the armature conductors of practically all direct current generators is alternating, and in order to obtain a unidirectional E.M.F. at the terminals of the the machine, it is necessary to reverse the connection at the moment the induced E.M.F. changes its direction.

A Study Of Induction Motors, Michael P. Valle

Bachelors’ Theses

The induction rotor is tho most popular type of alternating current motor, and finds a wide field of application, Its action is based on the principle of the revolving magnetic field produced by alternating current displaced in phase relative to each other. At least two currents of different phase are necessary in order to produce a revolving field.

A Test To Determine The Operating Efficiency Of A Steam Driven Electric Power Plant, Walter H. Rosemeyer, Edward Walter Kane

Bachelors’ Theses

In this test it was desired to determine the amount of water evaporated per pound of coal, and the pounds of steam consumed by main engine per kilowatt-hour output. Because of the existing conditions the test was run on only one boiler but on account of the similiarity of construction the results on the other boilers were assumed to be practically the same. The coal used was Hocking Valley Screenings, abituminous coal, which, from tests conducted by the engineer to determine the fuel best suited to the conditions of the plant, was found to give the most economical results. Since …

Energy Loss In Commercial Condensers, Walter Roland Allen

Electrical and Computer Engineering ETDs

The investigation of the energy loss in condensers is one which electricians and experimenters have long carried on. Their efforts have been restricted chiefly to alternating currents. Many methods have been proposed and used with varying success. The losses in condensers are due to dielectric hysteresis and leakage. That the dielectric of a condenser becomes heated when an alternating current is applied to terminals has long been known. A condenser which has been charged does not lose its entire charge when it is discharged, part of it remaining as a residual charge. Kleiner used the thermo-couple embedded in the dielectric …

Electrolysis Mitigation Of The Underground Telephone Cable Plant Of The City Of Green Bay, Wisconsin, William J. O'Connor

Bachelors’ Theses

Prior to the fall of 1915, the Wisconsin public Service Company of Green Bay operated an electric street railway with an uninsulated negative rail return in the city of Green Bay, the track network with its relation to the underground cable sheaths of the Wisconsin Telephone Company as shown on the General Condition Map.

The Design Of An Isolated Storage Battery Plant, Ottomar Henry Henschel, Joseph Anthony Walter

Bachelors’ Theses

This thesis is respectfully submitted to the faculty of: the College of Applied Science and Engineering of Marquette University of Milwaukee Wisconsin by Ottomar Henry Henschel for the Degree of Bachelor of Science in Electrical Engineering, and Joseph Anthony Walter for the Degree of Bachelor of Science in Electrical Engineering.

With the object of divorcing the electrical equipment from the lines or The Milwaukee Electric Railway & Light Company, and thereby hoping to materially cut down the operating expenses of the University plant, this storage battery plant has been designed.
