...engaged in the study of the properties of electrical insulation. As is well known, electrical engineering involves the use of three types of materials: conducting materials such as copper and aluminum; magnetic materials such as iron and steel from which magnets are made; and insulating materials such as rubber paper, cotton, oils, porcelain, and other similar materials which have the property of insulating the electric circuit. It is only by employing insulating materials that electric currents can be made to flow in the electric conductors. Otherwise, they would leak away, and it would therefore be difficult to transmit power...
...grounds. With underground cables, however, the situation is entirely different. In the first place, it is not permissible to carry high-voltage lines into the centers of population because of the danger. Therefore, it becomes necessary to use underground cables. The ordinary high-voltage underground cable is insulated with paper tapes which are thoroughly dried, and then impregnated with insulating oils. This paper insulation is then surrounded with a lead sheath. Such cables behave most erratically. They may be tested in the factory at four or five times their working voltages, and yet in three or four months' service they...
...primary cause of cables breaking down in service is due to the fact that small voids or air spaces are formed within the paper insulation. With present methods of manufacture, these voids appear to be inevitable. When such voids form, a minute electric discharge takes place within the void; that is, small electric arcs form, and the molecules of air find themselves in an electric field which causes them to attain high velocities. This effect is called ionization. The ions then impinge on the paper and oil, and have the effect of a rapid and continual bombardment. They not only...
...More Sacco-Vanzetti Evidence", printed grave charges about President Lowell. Was not this news, or was it to be ignored as "the policy of sensationalism of one of a large number of radical journals," or were all the Crimson editors engaged in writing interviews with Gilda Gray? Perhaps the paper was all full; among the important items of news enjoyed by the Crimson's readers next morning were such sensations as "Pi Eta Announces Plans for Whoops Dearie", and "Gibson Terrace Lodgers Seek Aid in Feud with Crooning Felines...
...regret deeply that the Transcript misread your Editorial, "Mark of the Beast," on March 21, and trust that "Squirrel Cage", in this morning's paper, has been sufficient to appease the Crimson's trustees...
