HANDBOOK OF ELECTRICAL POWER DIST.(2ND EDN)

The Handbook of Electrical Power Distribution is a comprehensive reference work that covers aspects of electrical distribution engineering-theory, design philosophy, data and standards-essential for a practising engineer to design electrification schemes for small to large-scale projects. It makes available ready-to-use information and data that are otherwise scattered in technical literature and product specifications of manufacturers, which are essential for practically executing a job. The second edition of the Handbook has four new appendixes. Appendix-1 contains a worked-out design example, that of an electrical scheme of a power transformer manufacturing unit, which cites the section and entry number in the book pertaining to the detail that is being worked out, e.g., the basic building structure, soil resistivity, earthing requirement, lumen level, equipment details, power loads for existing and future expansion needs, etc. This is expected to serve as a practical guide on how to use the book effectively in an actual project design. Appendix 2 includes the definition of per unit quantities, information on selection of circuit breakers and protection relays, power distribution solutions for bus duct systems along with some worked-out examples. Appendix 3 provides a quick reference to some of the frequently-used fundamental theorems and mathematical techniques in ac circuit analysis. It includes an introduction to complex numbers, Kirchoffs law, potential divider theorem, current divider theorem, superimposition theorem, Thevenins theorem, Nortons theorem, maximum power transfer theorem and the star-mesh transformation. Appendix 4 covers the essentials of matrix operations.
