Designed primarily for both undergraduate and postgraduate courses, the aim of this volume is to examine good distribution design practices and teach students to avoid errors which have occurred in the past when transmission theory and practice have been applied to distribution systems. Particular emphasis is placed on the theoretical background to distribution system design, network voltage performance, the use of computers in network design, the problems of certain loads and the need to take more account of amenity requirements when designing networks. Examples of design problems and their solutions are included in the text.
