Our Electrical power grids primarily consist of three-phase AC circuits. This means that all electrical components, conductors, breakers have three components.
To such components and materials, we often use a single line diagram. Each line is represented by a single line instead of three or four conductors.
A single line diagram reduces the complexity of the system and makes it easy to read the power system.
In this white paper, you’ll learn the single line representation, different symbols and examples of the substation, transmission line, and distribution stations and how to represent them in simple and SCADA based systems.
