Paperback. Condition: New. Print on Demand. This book details the technological advancements that occurred in alternating current systems from the initial alternating current systems to the alternating current systems in use at the turn of the twentieth century. The book's primary focus is to show how alternating current replaced direct current in various electrical systems such as lighting, power, and transportation. The author describes the development of various types of alternating current systems, transformers, and other equipment used in these systems. The author also discusses the advantages and disadvantages of alternating current systems compared to direct current systems, and the challenges faced by engineers in the development and implementation of these systems. The book concludes by highlighting the significance of alternating current systems in the development of modern electrical power systems, and their continued importance in the present day.
