The size of the power system determines the number of drawings required. Exceptions include substations 600 volts and over. Even for a simple case like above, the SLD is useful, practically SLDs are used for power systems and substations containing thousands of components and devices. Overall plant single line diagrams show the electrical power distribution system, in simplified form, from the utility and/or generated supply to the load side of substation protection devices. Let’s redraw the single line diagram for above case:Īs you can see, the single line diagram is a clean representation of the overall system that provides the big picture of the entire power system.

For this reason, a single line diagram is used instead.Ĭonsider the schematic diagram of a three-phase generator that feeds a three-phase motor load: While analyzing these systems, the use of three lines (all three phases) makes the documentation work complex. The top end usually corresponds to the start of the scheme. In the single-line diagram we will see them represented as a line in which all the conductors are included. It’s the latter that makes single-line diagrams not just important but essential for AV.

These diagrams help show the overall intent of the system as well as make the signal path more understandable. All transmission lines, distributions lines, and power transformers are also three phases in nature. A regular house usually has at least 5 circuits. For AV system design projects, single-line diagrams (SLDs) are often used to depict the flow of audio, video, control, and data signals. Our electrical power systems primarily contain three phases of AC circuits. In this post you’ll learn what is Single Line Diagram and why do we need it. A Single Line Diagram or SLD is a simple visual representation of three phase power systems.
