  • Abridgment of ionization studies in paper insulated cables — II

    The power dissipated as ionization loss in impregnated-paper-insulated cables is much more harmful than the power dissipated in the solid dielectric. The paper presents methods of separating this ionization loss from the total dielectric loss. This separation is based on the assumption that the power loss in the solid dielectric varies as the square of the voltage, even above ionization. To verify... View full abstract»

    This paper describes a new carrier telephone system which is designed for use in the telephone plant as a substitute for open-wire line construction for circuits of shorter lengths than could be economically spanned by multi-channel types of carrier systems in use for longer distance transmission. This new system, which is known as the type D carrier telephone system, provides one additional talki... View full abstract»

  • Abridgment of reduction of sheath losses in single-conductor cables

    Publication Year: 1929, Page(s):20 - 25
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2051 KB)

    The use of single-conductor lead-covered cable for high-voltage, three-phase transmission lines results in sheath losses ranging from 25 to 300 per cent of the conductor losses for cables installed in separate ducts, unless special methods for the reduction of the losses are used. Some of these methods, while practically eliminating sheath losses, cause a-c. sheath potentials which may be injuriou... View full abstract»

  • Forces on magnetically shielded conductors

    Publication Year: 1929, Page(s):25 - 27

    The results of some simple experiments are given to show how the magntic force, acting upon a current-carrying conductor in a magnetic field, is affected as the conductor is shielded by surrounding it by a permeable shield. It is shown that the force on the conductor practically disappears if it is put inside of an iron pipe, but that the pipe experiences a force — the sum of the force in t... View full abstract»

  • Insulation the opportunity for research

    CONSIDERING the wide range of types of electric circuit, it is at once evident that an equally wide variety of properties, — electrical, mechanical, and thermal, — is demanded for their insulation. Experiment and research directed toward improvements in insulation, therefore, have an almost unlimited field of opportunity. An enormous mass of experimental data from experienced investi...

    Today it is apparently permitted that one take an occasional glance at the things that have been left behind in the climb up from the past without suffering the penalties imposed upon the ancients. Pillars of salt have given way to a show of reason. Foresight, is, however, denied to an amazing degree. View full abstract»

  • Abridgment of A-C. elevator motors of the squirrelcage type

    Publication Year: 1929, Page(s):32 - 36
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1391 KB)

    This paper sets forth the features of squirrelcage motor design which differentiate it from standard motors. Much of the paper is devoted to the two-speed motor with two separate stator windings having speed ratios of 2/1, 3/1, 4/1 and 6/1. The two-speed motor with a single winding is limited to the 2/1 ratio. Higher ratios are necessary for high elevator speed and low and accurate landing speed. ... View full abstract»

    The use of high-voltage power lines for carrier-current communication presents a number of difficulties not met in the use of simple communication circuits. This paper tells how these difficulties may be overcome without resorting to complicated transmitting and receiving equipment. The advantages of employing tuned choke coils are described. These chokes are used to isolate the communication chan... View full abstract»

    Under modern conditions of operation the ability of the component machines of a power system to hold in step during system disturbances has become of major importance in the choice of system layout and machine design. This situation has greatly stimulated activity in the study of the problems involved. This paper reviews the general problem in the light of recent analytical and experimental studie...

    Lightning phenomena are analyzed in the light of laboratory experience with high-voltage phenomena in the atmosphere. Special emphasis is placed on the effect of space charges in producing high local stresses when mobilized through channels of high conductivity caused by high temperatures. A detailed analysis is included of the steps through which air at atmospheric pressure passes when, due to ap... View full abstract»

    The success of the series capacitor in increasing the load capacity, as well as improving the regulation of those a-c. transmission lines on which it has been tried,2 promises to lead to its wide adoption. The high loading and excessive short-circuit currents entailed by the series capacitor have to be cared for by safety devices, and in order to be able to design and properly locate su...

    Calculations and tests on small models have indicated that power systems at or near the theoretical power limit could not be operated safely, since any slight disturbance would cause instability with the resultant separation of the power transmission system. Very often, tests on small models do not closely check the results obtained on the real system; therefore, as a result of certain troubles wh... View full abstract»
