What reading level is Voltage Testing of Cables book?
To quickly assess the difficulty of the text, read a short excerpt:
To 1, 000, 000 cir. Mil cable, and these values are plotted in Fig. 3. These tables and curves are very useful WALL OF INSULATION, 64 r - h i N. (OJ97mm. ) FIG. 3 RELATION BETWEEN d LOGIC D/d AND WALL OF INSULATION.
"d" AND "D" IN MILS in the application of the formula to cable testing, for the value of K only needs to be known to determine the allowable voltage test or proper diameter. When d is expressed in mils, K varies from 100 to 250 for rubber compounds, is about 250 for cambric, and for... paper with thin walls is much less than 250 but is greater than this for walls exceeding 10/32 in. (7. 95 mm. ) STANDARDIZATION OF VOLTAGE TESTS Until recently no attempt has been made to standardize volt- age tests on insulated wires and cables with reference to the theo- retical stress. The result is a chaotic condition of affairs. A very VOLTAGE TESTING OF CABLES 11 common rule has been to specify a test of 2J/ times the working pressure, the feeling being that this allows a good factor of safety.
