TESTING ELECTRICAL RAILWAY BONDS

Thesis for the Degree of Bachelor of Science in Electrical Engineering, College of Engineering, University of Illinois, Presented June, 1907Experiments. The first experiment was conducted to deter mine whether the current flowing thru the rails from the cars Operating would cause a drop in a good track great enough within the car length, to be measured with an ordinary milli-voltmeter. Apparatus was constructed as shown in Figs. And 3. Two strap irons, L, were bolted to the side bar of the truck. These were bent back under the truck and an oak board, 0 bolted to their lower ends over the rail. Angle irons R, were bolted to the board and set screws thru these held the brushes in place. The brushes were constructed by cutting #20 steel wire into lengths of 3 and soldering them together at one end, as shown in Fig. 3. Two of these brushes, A and C, (fig. 1)About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
