Introduction Ever since Professor Ryan presented his famous paper on “Transformers” before the Institute, in which attention was called to the lack of symmetry between curves of instantaneous values of current and potential applied to the transformer, numerous writers have discussed the subject from various view points.

The paper gives a brief outline of some of the important developments in oil circuit breakers which have taken place within the last two or three years. Ideal conditions require that the current should not reestablish itself after passing the first zero value following the opening of the contacts, and this emphasizes the value of high opening speed in a ...

  • Measurement of Grounding

    This chapter introduces the methods and instruments for grounding resistance measurement, the factors Influencing the result of fall‐of‐potential method, including the influence of overhead ground wires, the measurement method of potential distribution, and corrosion diagnosis method for grounding Grid.

  • Concept of an Ideal pn Junction

    This chapter briefly reviews the fundamental physical idea of a pn junction proposed by Dr W. Shockley. In addition, extentions and corrections of the fundamental idea are addressed.

  • Probabilistic Potential Theory

    The equivalence of the steady-state wave and diffusion equations leads to a solution technique for electrostatics problems, sometimes called probabilistic potential theory (PPT). This technique relies on a random-walk game with a set of rules for play and scoring, while physical terms such as electric field, charge, or energy never appear. The random-walk procedure described in this chapter is an interesting but unsatisfying way to solve the finite difference Laplace equation. If this procedure were used over many points on a grid to determine the voltages at all these points, some of the voltages will definitely fall outside the confidence interval. The chapter then describes a procedure in which the diffusion equation is solved without resorting to random walks, or for that matter to random numbers at all. Another approach to a random-walk solution is to eliminate the grid entirely.

  • Numerical Analysis Method of Grounding

    This chapter introduces the numerical methods for parameters of substation grounding systems in uniform and multi‐layer soil, including grounding resistance, touch voltage, step voltage, mesh voltage, ground potential rise, and potential distribution on ground surface over grounding grid.

  • Techniques for Solving AC Circuits

    This chapter is mainly devoted to the analysis of alternating current (AC) circuits, in which all the quantities (mainly currents, voltages, powers) vary as sinusoids over time. In addition, it deals with two kinds of circuits in which the quantities do not vary as sinusoids, namely the R?>L circuit (containing a resistor and an inductor) and the R?>C circuit (containing a resistor and a capacitor). The chapter introduces circuit branches, whose idealized behaviour can be mathematically described by other constitutive equations. Since these are differential equations, it shows that the corresponding components have some energy storage capability and are therefore called globally energy storage elements. The phasors circuit was introduced, showing that Kirchhoff's equations can be written directly in terms of phasors.

  • EMG Modeling and Simulation

    This chapter outlines the main components that should be considered in the development of physiologically based models of surface electromyographic (sEMG). One of the challenges in increasing the accuracy of current sEMG models is the correct identification of the model parameters. Parameter identification is particularly difficult for systems such as this in which it is not possible to accurately measure all of the physiological, anatomical, and physical properties of the system. The chapter explores the simulation of intramuscular EMG, in particular for clinical applications. One of the primary purposes of a modeling approach is to identify the mechanisms responsible for experimental observations. A successful EMG model can thereby help the researcher to relate the recorded electrical signal to the underlying processes associated with muscle contraction. Model validation remains one of the most challenging areas in EMG modeling.

  • Earthing of Electric Distribution Systems

    Earthing plays an important role in the safe and reliable operation of an electric network. The choice of earthing system, in both medium voltage (MV) and low voltage (LV) networks, depends on the type of installation as well as the network configuration. This chapter explains different methods of earthing equipment, distribution substations and MV and LV networks. System earthing or intentional connection of a phase or neutral conductor to earth is for the purpose of controlling the voltage to earth within predictable limits. The neutral earthing methods used in MV networks can be classified into five categories: direct distributed neutral earthing, direct nondistributed neutral earthing, neutral earthing via impedance, neutral earthing via a designated circuit, and unearthed neutral. In compliance with IEC standard, three main earthing systems are used: IT earthing system, TT earthing system, and TN earthing system.

  • Grounding System for Substations

    This chapter introduces the purpose, design criteria and design methods of substation grounding systems, the methods to decrease grounding resistances of substations, and the equipotential optimal arrangement of grounding grid.

  • Detection and Conditioning of Surface EMG Signals

    This chapter presents the detection and conditioning of surface electromyographic (EMG) signals. More advanced techniques are now widely used in research laboratories and are being adopted in clinical settings. Such techniques are based on multichannel detection by means of one dimensional (1-D) or two dimensional (2-D) electrode arrays. The chapter describes the electrode-skin interface and the front-end amplifier stage. The impedance between two electrodes is the sum of two electrode-skin impedances plus the interposed tissue impedance. Conventional electrodes, either wet or dry, behave like transducers converting ionic current (in tissue and gel) into flow of electrons in the metal. These electrical sensors require a careful skin preparation to reduce the impedance and noise associated to this interface. The biomedical sector offers small-sized, high-cost application-specific integrated circuits (ASIC) devices for biopotential measurements. Applications are expected to range from physiopathological investigations, to rehabilitation games, biofeedback applications, and sport training.

  • Techniques for Information Extraction from the Surface EMG Signalhigh-Density Surface EMG

    This chapter deals with the information that can be extracted from images obtained when electrode grids are applied to the skin above muscles with different architectures. The interpretation of these images, and therefore the information obtainable, depends on the muscle architecture and fiber arrangement. The action potentials propagating along muscle fibers generate electric fields in the surrounding conductive medium. The chapter deals with the surface EMG instantaneous images, with the feature images, and with the spatiotemporal images. It provides examples on the information that may be obtained from high-density surface EMG (HD-EMGs) detected from muscles with pinnate architecture. Two main fields of research application of HDsEMG may be identified such as surface EMG imaging and surface EMG decomposition. From the clinical point of view, the expected developments concern more extensive applications in biofeedback and monitoring of the neuromuscular system for prevention purposes and automatic detection of the innervation zone.
