    The suitability of the newly developed polyethylene- insulated sodium conductor for use in electrical power cables was evaluated electrically and mechanically. Polyethylene-insulated sodium conductors are shown to lend themselves to a wide range of constructions manufactured on standard cable-fabricating equipment. Because of the plastic nature of metallic sodium, neither conductor stranding, nor ... View full abstract»

    Stabilization of the initial interconnection across Utah and Arizona between the Northwest and Southwest power systems has been aided by damping torques generated through special control of a unit in Grand Coulee powerplant in Washington. The special control is derived from local frequency, using the phase advance of the first derivative to offset the inherent lags of the hydro unit. The scheme is... View full abstract»

    The linear governing equations of L. M. Hovey are extended to describe the major nonlinearities of a hydro electric generating set. The resultant nonlinear governing model can be used to simulate the small and large signal transient response of an isolated generating set under any loading condition, and comparisons of such simulations with test results are given. The analysis of the paper demonstr... View full abstract»

    This paper describes an induction motor which has an additional dc field on the shaft. The dc field is free to rotate inside an independently rotating squirrel cage and it serves the purpose of improving the input power factor. The performance equations are derived, steady-state conditions discussed, and test data presented. View full abstract»

    The development of solid-state frequency converters or inverters makes the induction motor a possible machine for the final drive of a position control system, especially in power sizes. This paper analyzes the transient behavior of induction motors under conditions of changing supply frequency. The analysis is achieved by considering the squirrel cage as a 2-coil rotor and it is shown that this r... View full abstract»

    As voltage of electrical transmission systems increases, live line maintenance by the barehand method becomes increasingly necessary to meet the requirements of system reliability. Of more importance is its value to the workman in permitting him to use power and hand tools without the strain which would be encountered with the long, heavy, hot line tools required at these voltages. Protection of t... View full abstract»

    Twenty-two male mice were exposed to a 60-Hz ac electric field by placing them, in cages, between parallel plates energized to create a field, initially unperturbed, of 4 kV/in. In the course of 10¿months, each animal had an accumulated exposure time of nearly 1500 hours. These animals, and a parallel control group (essentially identically handled but receiving no exposure to electric fields), we... View full abstract»
