  • The economical speed control of alternating-current motors driving rolling mills

    Publication Year: 1912, Page(s):2173 - 2203
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2706 KB)

    For reasons which need not be discussed in this paper the induction motor has been adopted almost exclusively for driving rolling mills where electrical equipments have been installed. One of the most difficult problems to be solved with this type of motor when electrifying rolling mills is the speed regulation required for the merchant and hand mills, owing to the fact that this type of motor is ...

  • Comparative tests on high-tension suspension insulators

    Publication Year: 1912, Page(s):2204 - 2230
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (17468 KB)

    This paper presents an account of work done in connection with the selection of a suitable high-tension insulator for a transmission line operated at 110,000 volts. It is a report of an investigation giving a faithful account of the motives calling for the same, the method adopted and used to carry out the work, and the line of reasoning followed in classifying the results obtained. It is not inte... View full abstract»

  • High frequency tests of line insulators

    Publication Year: 1912, Page(s):2231 - 2254
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2017 KB)

    The object of this paper is to present for consideration certain very interesting and suggestive high frequency insulator tests recently made by the authors. These tests were undertaken to determine the availability of a certain insulator for use on a projected 38,000-volt line and resulted in a radical modification of the design. Having a strictly utilitarian purpose in view, these tests were not... View full abstract»

  • Discussion on “the use of reactance in transformers,” (Moody) and “the effect of temperature upon the hysteresis loss in sheet steel.” (Maclaren) New York, October 11, 1912. (see proceedings for October, 1912)

    Philip Torchio: Mr. Moody states that outside reactances arc equally effective and in practice superior to reactance within the transformer. Different attempts have been made to obtain a design of such reactances that would give the best results as to economy and safety, and also meet with the operation and installation requirements in stations. Mr. Moody gives in Figs. 4 and 5 views of a drum-wou... View full abstract»

    John W. Lieb, Jr.: The Institute owes a debt of gratitude to our distinguished fellow member from Chicago, who has presented such a vast and important economic proposition so lucidly and convincingly, and who has come before us and with such frankness and without reserve, has given us the benefit of the experience of his company, and of the advantages which have accrued to it from his far sighted ...

  • A visit to the Panama Canal

    I was fortunate in being able to make the Panama trip as one of the A. I. E. E. party which sailed from New York last January 17th, joining the New Orleans contingent upon our arrival at Colon January 25th. Here we were greeted by the receiving party composed of Colonel Seibert, a member of the Canal Commission and in charge of the Atlantic Division of the work, Mr. Schildhauer, the electrical and...

  • Discussion on “thirty years' progress in the electric furnace” (Fitzgerald), Boston, Mass., June 25, 1912. (see proceedings for June, 1912)

    Carl Hering: I am very glad to see that Mr. FitzGerald emphasized the fact that the cost of the energy is not the principal item in an electric furnace; so many people seem to think that it is; the cost of the electrodes, the cost of the furnace, the saving of labor, the better quality of the product, etc., should also be considered. If the product is more valuable you could stand a greater cost, ... View full abstract»

  • Discussion on “electrical measurements with special reference to lamp testing” (Edwards), and “incandescent lamps as resistances” (Amrine), Boston, Mass., June 28, 1912. (see proceedings for June, 1912)

    Clayton H. Sharp: Speaking of the paper by Mr. Edwards, the author gives a curve of corrections for the alternating-current voltmeter as used in checking the voltages on the life testing rack. He emphasizes the importance of that correction curve. I do not think he emphasizes it quite enough and I doubt if a laboratory standard voltmeter alone, even though carefully checked, is quite sufficient to... View full abstract»

    George D. Shepardson: Attention is called in the paper to the irregularities in the oscillograph curves at the values 332 cycles and 1292 cycles. I examined that “dimple,” as it is called, with considerable interest, and found two possible explanations for it. In both cases the dimple occurs where the diaphragm is at the greatest distance from the magnet. The first explanation which ... View full abstract»

    W. H. Pratt: Dr. Agnew's paper tells about the usual procedures in making a wattmeter for high current measurements, by stranding the conductor. Now, stranding the conductor must necssarily be done in a very careful manner, otherwise troubles will be encountered, but it performs two functions; it prevents the formation of eddy currents due to the field of the current coil itself, and it also preve...

  • Discussion on “potential transformer testing” (Craighead), and “the testing of instrument transformers” (Agnew and Silsbee), Boston, Mass., June 28, 1912. (see proceedings for June, 1912)

    Clayton H. Sharp: Regarding the last statement of Dr. Wenner, in his abstract of the paper by Messrs. Agnew and Silsbee, I find it rather surprising, inasmuch as the identical method for testing current transformers, with the exception of the vibration galvanometer detector, has been in use in our laboratory for two or three years, and a description of it was presented to the convention of the Ins...
