01 Oct 1997TL;DR: The second edition of a bestseller as mentioned in this paper covers all aspects of testing and maintenance of the equipment found in electrical power systems serving industrial, commercial, utility substations, and generating plants.
Abstract: The second edition of a bestseller, this definitive text covers all aspects of testing and maintenance of the equipment found in electrical power systems serving industrial, commercial, utility substations, and generating plants. It addresses practical aspects of routing testing and maintenance and presents both the methodologies and engineering basics needed to carry out these tasks. It is an essential reference for engineers and technicians responsible for the operation, maintenance, and testing of power system equipment. Comprehensive coverage includes dielectric theory, dissolved gas analysis, cable fault locating, ground resistance measurements, and power factor, dissipation factor, DC, breaker, and relay testing methods.

TL;DR: In this article, a deterministic, non-iterative method using an holomorphic embedding and algebraic approximants for determining the real-time load flow in a power generating system having an electrical grid is presented.
Abstract: A system and method for monitoring and managing electrical power transmission and distribution networks through use of a deterministic, non-iterative method using an holomorphic embedding and algebraic approximants for determining the real-time load flow in a power generating system having an electrical grid. Such method may be employed for real-time or off-line applications for electric power systems reliability assessment, and is capable of determining whether or not a physical solution to the load flow problem exists, or if the system is in a state of voltage collapse.

TL;DR: In this paper, the relative motion of the ribs can be used for periodical stretching of a converter, which can be converted into electric power to supply implants which require a permanent power source.
Abstract: A fraction of the energy expenditure for respiration can be converted into electric power to supply implants which require a permanent power source. Toward this goal the relative motion of the ribs can be used for periodical stretching of a converter. A miniaturized prototype with solid electrical and mechanical contacts has been designed. We describe here the physical characteristics of the device and present the first results of an animal experiment. With improved PVDF films, a power converter with a film mass of a few g could supply implanted electric systems with a power of 1 mW.

19 Nov 2002TL;DR: In this paper, the authors measured the communication quality levels of all lines of the wireless and electric power lines, and selected the communication line having the highest communication quality level to be used for communication.
Abstract: From an electric pole outside to a cordless handset inside a building/facility, a communication line is established via an electric power line. At this point, it is judged whether or not electric power line communication is possible, and if electric power line communication is possible, the communication line between the cordless handset and a base unit is switched to an electric power line communication system, and a communication line is formed via an optical fiber cable from the electric power line. By measuring the communication quality levels of all lines of the wireless and electric power lines, the communication line having the highest communication quality level may be selected.

TL;DR: In this article, catalytic microcombustors are integrated with thermoelectrics to produce electricity, and they are found to be robust, easy to start up, and able to support complete combustion over a range of fuels (e.g., C3H8/air and H2/air systems) at different flow rates.
