What is electric power distribution? 3 • Electric power distribution is the portion of the power delivery infrastructure that takes the electricity from the highly meshed, high-voltage transmission circuits and delivers it to customers. • Some also think of distribution as anything that is radial or anything that is below 35 kV.
2 FUNDAMENTALS OF ELECTRICAL DISTRIBUTION We will start with an overview to introduce you to the main points about these devices, and the parts that make them. Then we will step through each of these topics in detail: Section Title Page Number • Electrical Distribution System 3 • Radial Distribution System 3 • Loop Distribution System 4 • Network Distribution System 5
