    Computer simulation is designing a model of an actual or theoretical physical system, executing the model on a digital computer, and analyzing the execution output. Simulation embodies the principle of “learning by doing”-to learn about the system we must first build a model of some sort and then operate the model. Children understand the world around them by simulating (with toys and ... View full abstract»

    Programmable logic controllers (PLCs) are at the forefront of manufacturing automation. Many factories use programmable logic controllers to cut production costs and/or increase quality. PLCs and their unique language, ladder logic, are the workhorses of factory automation. Higher-level languages, such as sequential function charts and function blocks, ease the programming task for large systems. ... View full abstract»

    Discusses various properties of the metal rhenium. The properties include: malleability, high-temperature strength, resistance to carburizing and high electrical resistivity across a wide temperature range. This makes rhenium a great candidate for applications where high-temperature strength, wear resistance and erosion resistance is needed View full abstract»

  • Adaptive relaying. A new direction in power system protection

    Publication Year: 1996, Page(s):28 - 33
    Cited by:  Papers (4)

    The authors describe adaptive relaying, a new philosophy in protecting electric power systems. Adaptive relaying utilizes the continuously changing status of the power system as the basis for online adjustment of the power system relay settings. Consequently, it provides the required flexibility for obtaining very high levels of power system reliability. Digital relays with adequate software and c... View full abstract»

    Some assignments, both civilian and military, are better performed by unmanned, long-endurance, solar rechargeable aircraft high in the atmosphere than by satellites in low Earth orbits. These aircraft would have more flexible flight paths and would be far less costly than satellites to design, build, and operate. In collaboration with AeroVironment, Inc., the authors developed a lightweight flyin... View full abstract»

  • A watt-hour meter-the solid state polyphase kind

    Publication Year: 1996, Page(s):9 - 13
    Cited by:  Papers (2)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1292 KB)

    The old watt-hour revenue meter with its rotating disc is a familiar sight at every electric service entrance, be it residential, industrial, or commercial. However, modern technology has made a solid state version economical for most new polyphase metering installations. Polyphase metering is the norm for all industrial and many commercial consumers. This is because the large power levels and pol... View full abstract»

  • Surge arresters. Protecting equipment from heatstroke

    Publication Year: 1996, Page(s):34 - 36

    The authors outline how the main consideration for properly designing a ZnO arrester is the thermal behavior of its components (i.e., their heat transfer properties). They argue that the analysis should be carried out not only in the steady-state of the device, but also in the dynamic and the transient states. Each element must be designed so that the energy handling capability of the assembly is ... View full abstract»
