The 1200-volt railroad — A study of its value for interurban railways

Proceedings of the American Institute of Electrical Engineers, 1910

The various 1200-volt interurban railways have now been operating a sufficient length of time to prove that there are no material objections to the use of this voltage on passenger cars. The nature of such minor difficulties as have been experienced have been such that their correction has required only detail changes of design which have been readily made. The ...


Study on Protection of HTS Coil Against Quench Due to Temperature Rise of Long Part of HTS Wires

IEEE Transactions on Applied Superconductivity, 2013

Generally, high-temperature superconducting coated conductors (CC) are hard to be quenched by local and transient disturbances during normal operation because of the high temperature margin and high heat capacity of the conductor. However, the CCs still have possibilities of unexpected quenches originated by the appearance of local defects due to repeated mechanical stresses, and by temperature rise of the long ...

Forced-oil and forced-water circulation for cooling oil-insulated transformers

Proceedings of the American Institute of Electrical Engineers, 1907

IEEE Transactions on Applied Superconductivity, 2011

We have studied aging in laser ablated 2 wt% BaZrO3doped GdBaCuO (GdBCO) thin films. The films were coated with gold, silver, copper, photoresist and stycast. One film was left without coating for reference. The superconducting and structural properties were followed for several months. The critical temperature_Tc_and current density_Jc_were determined from magnetization measurements. The changes in structure were investigated with x-ray ...

  • The 1200-volt railroad — A study of its value for interurban railways

    The various 1200-volt interurban railways have now been operating a sufficient length of time to prove that there are no material objections to the use of this voltage on passenger cars. The nature of such minor difficulties as have been experienced have been such that their correction has required only detail changes of design which have been readily made. The important items of reliability and low cost of upkeep have met all expectations.

  • Study on Protection of HTS Coil Against Quench Due to Temperature Rise of Long Part of HTS Wires

    Generally, high-temperature superconducting coated conductors (CC) are hard to be quenched by local and transient disturbances during normal operation because of the high temperature margin and high heat capacity of the conductor. However, the CCs still have possibilities of unexpected quenches originated by the appearance of local defects due to repeated mechanical stresses, and by temperature rise of the long part of the CCs due to malfunction of the cryogenic system, for example. In this work, the hot spot temperature of a CC with copper stabilizer during quench protection sequence is calculated by a numerical analysis for quenches by both of the origins mentioned above. The practical amount of the stabilizer is discussed not to over-protect but for a coil system to surely survive from sever damages caused by quenches considering quench origins.

One film was left without coating for reference. The superconducting and structural properties were followed for several months. The critical temperature_Tc_and current density_Jc_were determined from magnetization measurements. The changes in structure were investigated with x-ray diffraction (XRD). It was found that in all the films the superconducting properties deteriorated more than can be accepted during the aging time.

  • Optical fibers reach into homes

    The replacement of the standard series-connected pair of twisted copper wires that connects each home to the telephone network today by optical-fiber cabling that can handle broadband services is discussed. The technologies needed for the fiber to the home, which are dominated by such considerations as bit rates, network architecture, and power dissipation, are discussed. Various combinations of services and technologies that are currently undergoing trials are described. Future evolution into broadband networks is discussed.<<ETX>>

  • Design, construction and test of an artificial transmission line

    A little over a year ago Dr. Steinmetz suggested the construction of an artificial transmission line or “slow-speed conductor” in the Electrical Laboratory at Union College. It was proposed to duplicate or reproduce as nearly as possible the conditions of a high-voltage long-distance transmission line in the laboratory in such a way that the various phenomena connected with a line of this sort might easily be investigated. It was not desired particularly to study the effects of very high voltage but rather to investigate and study the various transient and other phenomena in connection with switching, sudden change of load, etc.

  • The influence of pre-heat treatment on peeling resistance of oxide film of copper alloy lead frames

    The peeling resistances of oxide film formed on copper alloy lead frames with and without pre-heat treatment were investigated. With the increase of the heat treatment temperature, the peeling resistances of oxide film of C194 decrease, while C7025 show little variances in contrast. Crystal orientation of copper alloy with and without heat treatment was examined by XRD. Compared with peeling test results, it is proved that the surface crystalline orientation of cooper alloy has crucial impact on the cohesive strength between the oxide film and copper substrate. When the surface follow (111) close-packed face, the oxide film forms with better peeling resistance property, otherwise the peeling resistance will deteriorate. Furthermore, peeling resistance of oxide film has correlation with the precipitated phase.

  • Development of Low-Fluorine Solution for YBCO Film Growth

    We developed a simple and stable precursor solution containing low fluorine content to fabricate YBa2Cu3Oy(YBCO) films on CeO2/YSZ/CeO2buffered NiW substrates. The fluorine content in the precursor solution could be controlled at 23.1% by tuning the ratio of barium trifluoroacetate to barium acetate. Fast pyrolysis process and smooth surface of YBCO precursor films could be acquired by using the low-fluorine solution. The phase, texture, microstructure, and superconducting properties of YBCO film were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscope, and four-probe method, respectively. The crystallized YBCO film showed good out-of-plane and in-plane textures. A high critical current density Jcof ~3 MA/cm2(77 K, 0 T) could be obtained in the YBCO/CeO2/YSZ/CeO2/NiW sample derived from the low-fluorine solution. The results indicate that the controllable fluorine content solution could be useful for epitaxial growth of YBCO films on buffered NiW substrates.

  • The design of induction motors

    At the last International Electrical Congress, the writer presented a paper on the “Leakage Reactance of Induction Motors,” in which a new leakage element was described, with results of experiment and calculation. A method of calculating the other leakage elements was also outlined. This method, based upon fundamental principles, was checked by a long series of experiments, and while not new fundamentally, may have some points of novelty in its details. In the present paper this method will be more fully developed and applied to the design of Induction Motors. The leakage elements will be expressed in a novel form and a new method will be employed for the calculation of the power factor. A method of calculating the exciting current will be given with corroborative data. Some new design constants will also be developed.
