    Here is given a résumé of the accomplishments to date in the long-continued efforts toward ever-improved operating economy in steam-electric generating stations. Facts seem to indicate that the engineers of the future will meet the challenge of past accomplishments by building stations of still higher fuel economy and still lower cost per unit of capacity.

    Much of the data on impulse voltage testing of insulators and insulation which has been given out in the past has been obtained on a basis that renders it of little value for purposes of comparison and coordination. To clarify this situation the lightning and insulator subcommittee of the A.I.E.E. power transmission and distribution committee has conducted a study, the results of which are reporte...

  • The principle of condenser discharge applied to Central station control problems

    Publication Year: 1933, Page(s):41 - 42
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (322 KB)

    APPLICATION of a resistor connected in series with a condenser as a means for indicating the rate of change of a d-c potential is described in this paper. When the potential is varied the condenser will charge or discharge through the resistor, and the charging current will produce a voltage drop across the resistor. This voltage drop is approximately proportional to the rate of change of the appl... View full abstract»

  • High velocity vapor stream in the vacuum arc

    Publication Year: 1933, Page(s): 42
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (171 KB)

    Blasts of vapor have been discovered in the last few years to issue at high velocity from the cathode region of a vacuum arc. The consideration of this subject is important in the study of the arc. Previous theories of the cathode of an arc which have not taken account of the vapor stream must be extended, for the vapor blast, as it now appears, is a part of the cathode phenomena and as such must ...

    Publication Year: 1933, Page(s): 43
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (203 KB)

    EFFICIENCY of train operation depends largely upon a system of directing train movements that will insure the maximum utilization of track and equipment capacity and the maximum output of train miles in a unit of time. In the earlier days the time interval method of railway signaling was favored, movements being directed by timetables and train orders. The space interval method is now universally ...

    MOST modern signal systems have many features of interlocking and signal control that are common to each other. A description of the signal system on one railroad, therefore, may be of interest to others. Following a brief outline of the earliest forms of signaling employed on the Reading Railroad, this paper describes the Reading's most recent installation of 100-cycle a-c color light signaling. ...

    CENTRALIZED traffic control systems concentrate at one point under the direction of one operator the control of train movements over a long section of track, and expedite the movement of traffic in that section. This is accomplished by bringing within view of the operator, indications as to the location of trains and the position of all switches and controlled signals, and also by bringing within ...

    SELF-EXCITING a-c commutator generators have for some time been considered as sources of electrical power. However, what is probably the first commercial use of this type of generator as the prime source of energy for a power machine has recently been made. It is a 6-pole 1,200-rpm 3-phase machine rated 40 kva, 235 volts, 2.5 cycles, and is driven by a squirrel cage induction motor. The set suppli... View full abstract»
