Book Description

Excerpt from Switching Equipment for Power Control It will also assist him in the selection and installing of new material. The secondary object is to help the student of electrical engineering in a technical school to get a better understanding of this branch of the art and to appreciate how the switching equipment ties together the various generators, transformers, feeders, etc., that make up the component parts of a generating and distributing system. Consulting engineers and others will find enough of the theoretical features to give them an understanding of the functions and limitations of the various devices. Such an understanding will facilitate specifying equipment that can be readily obtained and that will operate satisfactorily under actual conditions. The arrangement of this book has been based on the idea of first describing the switching apparatus, approximately in the order in which the various devices were developed. This is followed by considering the main connections desired in a power plant and the means for carrying out the connections so as to obtain the maximum amount of security and flexibility with the minimum outlay. Switchboard panels, control desks, etc., are considered next with the location of breakers, bus structures, etc., and the general arrangement of the part of the power plant devoted to switching equipment. Description of apparatus has been confined almost exclusively to present day standards to keep the subject matter down to a reasonable length, but a few references have been made to some of the older types of apparatus to show the progress of design. American practice, forms the basis for the descriptions and most of it is the practice of the largest electrical manufacturers. The attempt has been made to include descriptions of apparatus of other important builders, but it has been impossible to describe all of the apparatus of all the builders. The data has been obtained from various sources and the most readily available material has been used. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
