ABSTRACT
This is a technical report presented on the design and construction of an Automatic Phase Selector.
In the construction work, an ordinary level knowledge of electronics principles are observed. We aimed at presenting a practical aspect of the subject and then providing the argument necessary for a thorough understanding. The reliability of the specimen was estimated after construction and testing to ensure steady state stability. The work is organized into five chapters.
Chapter one introduced the subject matter. Chapter two explores the literature review of the related works. Chapter three contains a detailed account of the design work while chapter four closely attempted an analysis of the design work. Chapter five draws the curtain by concluding the work.
