Practical Methods for Analysis and Design of HV Installation Grounding Systems gives readers a basic understanding of the modeling characteristics of the major components of a complex grounding system. One by one, the author develops and analyzes each component as a standalone element, but then puts them together, considering their mutual disposition, or so-called proximity effect. This is the first book to enable the making and analysis of the most complex grounding systems that are typical for HV substations located in urban areas that uses relatively simple mathematical operations instead of modern computers. Since the presented methods enable problem-solving for more complex issues than the ones solved using National, IEC and/or IEEE standards, this book can be considered as an appendix to these standards. - Develops general equations of lumped parameter ladder circuits - Includes the analytical expression for determination of ground fault current distribution for a fault anywhere along a cable line - Presents measurement and analytical methods for the determination of actual ground fault current distribution for high-voltage substations located in urban areas - Provides the analytical procedure for the determination of the critical ground fault position for faults appearing in outgoing transmission lines - Defines testing procedure for the correct evaluation of grounding systems of substations located in urban areas

The problems of system grounding, that is, connection to ground of neutral, of the corner of the delta, or of the midtap of one phase, are covered. The advantages and disadvantages of grounded versus ungrounded systems are discussed. Information is given on how to ground the system, where the system should be grounded, and how to select equipment for the grounding of the neutral circuits. Connecting the frames and enclosures of electric apparatus, such as motors, switchgear, transformers, buses, cables conduits, building frames, and portable equipment, to a ground system is addressed. The fundamentals of making the interconnection or ground-conductor system between electric equipment and the ground rods, water pipes, etc. are outlined. The problems of static electricity(how it is generated, what processes may produce it, how it is measured, and what should be done to prevent its generation or to drain the static charges to earth to prevent sparking(are treated. Methods of protecting structures against the effects of lightning are also covered. Obtaining a low-resistance connection to the earth, use of ground rods, connections to water pipes, etc, are discussed. A separate chapter on sensitive electronic equipment is included.

Learn the theory behind grounding systems and bonding equipotential connections from a worldwide expert. Through mathematical analysis, comprehensive explanations, and detailed figures, Analysis of Grounding and Bonding Systems explains the theory and the reasons behind basic ground-electrodes (i.e., the sphere, the ground rod, and the horizontal ground wire), and more complex grounding systems (i.e., ground-grids), buried in uniform and non-uniform soils. Through calculations and explanatory diagrams, this comprehensive guide provides code-complying solutions for the safety against electric shock provided by equipotential bonding connections between exposed-conductive-parts, such as equipment enclosures, and metalwork. Details on the calculation of step and touch voltages in different types of system grounding (i.e., TT, TN, and IT) are provided, also with the aid of solved problems. Readers will learn how to minimize hazardous interactions between grounding systems, cathodically protected pipelines, and heat networks. The analysis of the effectiveness of bonding systems against electric shock in the case of contact with electric vehicles during charge in the event of ground-faults, which is an upcoming issue challenging our safety, is included.
