This book includes my lecture notes for electrical power distribution book. The fundamentals of electrical power distribution are applied to various distribution system layouts and the function of common distribution system substations and equipment. The book introduces the design procedures and protection methods for power distribution systems of consumer installations. Circuit simulation and practical laboratories are utilised to reinforce concepts. The book is divided to different learning outcomes • CLO 1- Discuss the fundamental concepts related to electrical distribution systems. • CLO 2- Explain the role of distribution substations and related equipment. • CLO 3- Outline standard methods for power distribution to consumer installations. • CLO 4- Apply short-circuit and over-load protection principles for electrical installations
