    THE reaction synchronous motor in its present form (salient-pole rotor without field coils) is one of the oldest types of electric motors, antedating the induction motor by many years. At first it was used only in connection with instruments, such as the oscillograph etc.; later its simplicity and exactness in keeping in step made it the standard driving motor for rectifying devices such as are us...

    Accidental arcing grounds on transmission lines constitute the foremost problem to be solved in the transmission of electrical energy over great distances. There has come into use to a limited extent, arcing ground suppressors. This device consists in principle, of a switch in the station which is automatically closed in parallel with the accidental arc at any point out on the system. The parallel... View full abstract»

    The main purpose of this article is to express the calculation of current-carrying capacity in simple formulas. The allowable current for underground cables is usually limited by the maximum permissible temperature of the insulation. The temperature rise is of course a function of the ability of the cable system to dissipate the heat generated. The chief difficulty in the calculation of current-ca... View full abstract»

    THE disposal of the heat resulting from the electrical and mechanical losses in any electric machine is always an important item to the designer as well as to the operator of the machine. These losses appearing all in the form of heat must be transferred from their source with a temperature gradient not to exceed the maximum safe operating temperatures.

    The use of so-called “artificial lines” — i.e. miniature models of electric circuits — for experimental laboratory studies of transmission-line phenomena is well known.

    ANYONE familiar with the design of air-core inductances knows, that for a given resistance, the size and weight of the coil rapidly increase as the inductance is increased. Though the increased cost due to this increase in weight may not be of great importance, it is evident in many types of apparatus in which such coils play an essential part, as in portable radio sets, that both weight and size ...

    There has been a rather prevailing opinion that a sudden short circuit of an induction generator would not cause a serious initial rise in current such as occurs in synchronous generators. This has led to the proposal of the use of such machines as a partial solution of the short-circuit problem on a-c. systems.

    Heretofore the distance to which power could be transmitted has been limited. This limitation is now removed by a simple method of loading the line with synchronous condensers, so that the current and voltage may be kept practically in phase. High power factor and hence high efficiency result, and the voltage rises of the system are very much reduced, thus reducing insulation strains. A standard f... View full abstract»

    A power amplifier may be so connected to the circuit supplying the power to be amplified that it introduces terms into the equation for the current in the power circuit which subtract from the resistance terms.

    The method proposed makes use of idle operation of the machine as a motor, the voltage being varied, and speed kept constant.

    The resistance of metallic conductors is higher for alternating currents than for direct currents, due to the so-called “skin-effect”. With alternating currents, the distribution is not uniform throughout the cross-section, there being a tendency for the current to concentrate towards the outside of the conductor, thus causing an increase of resistance and consequent increase of powe...
