    The synthesis of the principal types of inverters that are best suited for static uninterruptible power supplies (UPS) is sought. From this synthesis a range of apparatus is evolved that will satisfy present and future needs. For each point of this range new solutions are indicated; their development is tied with the technological evolution of the components. The reliability and redundancy aspects... View full abstract»

    Corrosion that occurs in the presence of dissimilar metals in the same electrolyte, or same metal in different electrolytes, or in different concentrations of the same electrolyte, has caused numerous problems in operating electric systems. This corrosion is the result of a potential difference existing between two surfaces which forces an electric current to flow. This effect is often ignored or ... View full abstract»

    Laboratory tests of arcing faults trapped between a corner of a simulated steel housing and single or multiple bus bars were found to be reasonably reproducible and caused relatively consistent burning damage. Single phase 277-V arcing fault tests using spacings of 1 to 4 in from bus bars to ground at current levels of about 3000 to 26 000 A indicate that damage is proportional to I1.5t. In...

    Cited by:  Papers (85)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3952 KB)

    A dynamic model for current-controlled induction motor drives is developed, and a transfer function approach to the transient response investigation is formulated by means of d-q variables in the synchronously rotating reference frame. A sample control strategy is discussed, and transfer functions for various combinations of input and output variables are presented. It is shown that both dynamic a... View full abstract»

  • A Process for Improved Induction Heating of Powder Metal Compacts

    An unusual ``incubation'' period is encountered at the beginning stages of medium frequency (3 kHz) induction heating of unsintered, low alloy, steel powder metal compacts. This incubation period is characterized by poor load coupling to the induction coil and consequently, very slow and inefficient heating. An unusually high material resistivity has been isolated as the cause of this incubation p... View full abstract»

  • A Comparison of Methods for Determining the Wattage Output and Energy Distribution in Microwave Ovens

    Publication Year: 1977, Page(s):335 - 342
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (4650 KB)

    Two characteristics of microwave ovens that are important to consumers as they select and use microwave ovens are the wattage output (cooking power) and the evenness of distribution of energy within the oven cavity. Several test methods have been proposed to measure each of these characteristics, but there is not agreement in the industry on realistic methods of their measurement. The purpose of t...

    Since the onset of the energy crisis, many floodlights have been dimmed or removed. The cost conscious building owners are more concerned with the energy costs than losing beauty and elegance of the buildings. In the last several years, many highly efficient light sources have sprung up on the market. Along with these light sources, many new fixtures are also available for doing a specific floodli...

    There is a wide assortment of complicated electrical charge-exchange phenomena that can occur when two materials are simply brought into contact and then separated. The relevant literature is extensive and complicated. Thus the literature on microscopic models of contact electrification is surveyed, and the essential features are systematically condensed so that comparisons can be readily made bet...

    Charging phenomena of small particles have been observed in the scanning electron microscope (SEM). Polystyrene particles, mounted on gold coated hologram grating substrates, are negatively charged by the primary beam in the SEM, and a significant distortion of the grating is seen. Computer generated images have been matched to the experimental images of gratings. Parameters related to the microsc... View full abstract»

    The variables and parameters of corona device design for positive dc corona are discussed as they affect uniformity and magnitude of plate current as the shield angle surrounding the wire is changed. Also presented are the effects of using either grounded conducting or insulating shields on the magnitude of positive dc plate current. View full abstract»

    Investigators at The University of Western Ontario, Canada have developed an apparatus for electrostatic separation of very fine particles. The dilute phase loop eliminates the entrainment problems generally associated with dry handling of particles below 40 ¿m. Results are presented for separation of two materials: 1) coal macerals; 2) carbon particles from fly ash. View full abstract»

    Stable, nearly sinusoidal, phase-coherent ion plasma oscillations have been consistently observed superimposed on the dc levels of positive coaxial corona discharges at air pressures of the order of a few torr. The frequency of these oscillations, typically several hundred kilohertz, has been found to be a function of air density and dependent on the presence and concentration of gaseous trace con...

    The inclusion of internal antistatic agents in nylon 6 and nylon 6,6 fibers increases their electrical conductivity to a much greater degree than does the inclusion of "normal" nonantistatic internal additives. Commercial antistatic additives generally raise the conductivity of nylon fibers by a factor of 1000 compared with standard commercial yarns and by a factor of 10000 compared with yarns mad...
