Types Of Diagrams:
Single Line Diagram:
Known as usually SLD, in addition, to a key line diagram, One line diagram is also used.
It gives us a basic understanding of the functions of the components of a system. The single-line diagram uses symbols to represent and shows all components. There is no interconnection shown for selected components. The single-line diagram is very simplified and should be used mostly to learn the function of each of the various components as a part of the total system.
The schematic diagram shows the details of each electrical component, showing each and every wire. The schematic diagram shows, by means of graphic symbols, the electrical connections and functions of a specific circuit arrangement. The schematic diagram is used to trace the circuit and its functions without regard to the actual physical size, shape, or location of the components devices, or parts. The schematic diagram is the most useful of all the diagrams in learning overall system operation.
Block diagram is a diagram of a system, in which the principal parts or functions are represented by blocks connected by lines, that show the relationship of the block. They are heavily used in the Engineering World in hardware design, software design, and process flow diagrams. A block diagram shows the major components of the system and the interconnection of these components. All components are shown in block form, and each is labeled for identification purposes.
Circuit Diagram:
A wiring diagram is a detail of each circuit installation showing all of the wiring, connectors, terminal boards, and electrical or electronic components of the circuit. It also identifies the wires by wire numbers or color coding. Wiring diagrams are necessary to troubleshoot and repair electrical or electronic circuits.
