    Because the noise created by power-plant equipment has sometimes caused complaints from those working in the plants and from residents living nearby, a survey of such noise was undertaken. This paper presents the results of this survey and shows how the power-plant noise levels compare with desirable levels. Descriptions of the particular equipment that produce most power-plant noise are included ... View full abstract»

    Insulating sheath coatings and sheath-joint insulators have been punctured in service, apparently by transient voltages. It has been shown that the discontinuities caused by sheath cross-bonding result in 15% of an applied surge on a conductor, appearing on the sheath at a joint and 30% across the sheath insulator. Bonding transformers result in higher transients. Protective devices appear to be r... View full abstract»

    The theory of monotonic scheduling is extended to hydrothermal systems with interconnections to adjoining power systems. The exposition is limited to the two most common types of interconnection arrangements, although the methods can be applied to other cases as well. All systems entering into this model are assumed to have thermal generation on line for the entire day. Variable-head hydraulic sta... View full abstract»

    Circuit power factor has long been used as a rough measure of circuit interrupting severity. Closer analysis reveals that with some types of modern circuit interrupters (fuses, magnetic air breakers, load break switches) new definitions must be sought to describe the true severity of the application and test circuits. This paper presents the nature of the problem to be solved. This new undefined d... View full abstract»

    By generalizing and expressing as an equation the significant quantities in any relationship it can be made apparent just how each term influences the answer sought. In this paper, a mathematical treatment is developed to define the economic balance between generating capacity having differing first costs and differing operating costs. This is done in terms of annual carrying charges, production c... View full abstract»

    Before high-voltage insulation is put into practical service, numerous tests are carried out to determine its mechanical, electrical, and thermal properties. Of prime importance is the dielectric strength. This should remain constant for a maximum period of time and is determined by voltage-endurance tests carried out until a breakdown takes place.1-3 Other important characteristics such as air co...

    By locating a hard magnetic material, such as Alnico, in the leakage flux paths of the secondary circuits of an induction motor, a remarkably high locked-rotor torque per ampere can be obtained, without sacrifice of full-load speed. This paper presents test data for both wound-rotor and squirrel-cage motors, using this Saturistor principle. The motors so made are series hysteresis (induction) moto... View full abstract»

    This paper describes a new form of polyphase induction motor, the series hysteresis motor, which derives most of its accelerating torque from the hysteresis losses produced in a hard magnetic material, located in flux paths linked by the secondry currents of the motor. The resulting torque curve is remarkably flat, and the torque per ampere unusually high (Fig. 13). View full abstract»

    Natural frequencies and surge response of the windings of 3-phase transformers have been determined in the past by neglecting the capacitive and inductive couplings between the phase windings. This paper shows that these assumptions are not valid and presents a new method of formulating equivalent networks of 3-phase transformer windings for the various winding connections and terminal conditions....

    Pressure-difference relations are given for the insulation of oil-filled pressure cables with fluted sheaths. Pressure differences are calculated for a 380-kv cable with such a sheath, and results are compared with those in a cable having a smooth sheath.

    A vernier motor is an unexcited inductor synchronous motor in which a small displacement of the rotor produces a large displacement of the axes of permeance. It runs at a slow speed as if it were geared down from the speed of the rotating field set up by the stator. To design a vernier motor is equivalent to designing a polyphase reluctance motor with an odd-shaped rotor so that the airgap permean... View full abstract»

    The high series capacitance theory for the response of interleaved transformer windings to surge voltages is criticized from the point of view that an increased series capacitance as a result of interleaving is incompatible with the concept of a pure capacitive initial voltage distribution. A new theory is proposed according to which the distributed earth capacitances are charged up during an init... View full abstract»

    Maximum voltage which can be insulated between a sphere and a plane has been measured as a function of gas pressure and gap. It is found to be approximately three times higher in SF6 than in N2+C02, up to pressures of roughly 9 atm (atmosphere). For higher pressures the relative superiority of SF6 over N2+C02 diminishes. Gradients of more than 100 Mv (million volts) per m (meter) were insulated on... View full abstract»

    A recently developed computer program will position both angle-and tangent-type towers on any given terrain. The towers are so positioned that the optimum cost per foot of line may be obtained, consistent with predetermined tower heights and types. Basically, the program's tower spotting procedure consists of a mathematical simulation of the established manual method of moving a transparent parabo... View full abstract»
