Single line diagrams are useful in planning a substation layout. – Example diagrams are attached for your information in preparing a Single Line Diagram. Single Line (Feeder) Diagram NEC 215-5. In single line representation of substation the electrical components such as power transformers, incoming and outgoing lines, bus-bars, switching and protecting equipments, are represented by standard symbols and their interconnections between them are shown by lines. The single line diagram is circuit diagram where "one-line" is shown to represent three phases of a three phase power system. The one-line diagram is similar to a block diagram except that electrical elements such as switches, circuit breakers, transformers, and capacitors are shown by standardized schematic symbols. Figure 3—One-line diagram Wiring Diagram Book A1 15 B1 B2 16 18 B3 A2. Line diagram: a one-line diagram or single-line diagram is a simplified notation for representing an electrical system. It comprises an enclosure in steel or plastic, a contactor, start contact, link wires and stop / start buttons. This is because the diagram shows multi-conductor cables with a single line. The Thermal overload is supplied as a separate item. View Lab Report - Single_line_diagram_autocad_example.pdf from EE 518L at Emilio Aguinaldo College.
