Electrical Installation Technology, Third Edition covers a wide range of subjects about electrical science, installations, and regulations. The book presents chapters tackling general principles and information about electromagnetism, inductance, static electricity, D.C. and A.C. circuits, and voltage drop and recurrent rating. The book describes distribution, wiring techniques, D.C. generators and motors, A.C. motors, and transformers. The importance of power-factor improvement, earthing and earth-leakage protection, and testing are also considered. The latter part of the book describes communication systems and equipment, such as batteries, cells, call systems, alarms, and electronics. The book concludes with a chapter dealing with important topics under site and office management. This book will serve as a textbook for students taking the Electrical Installation Technicians and Electrical Technicians Courses, and will also benefit electrical engineers.
