An One Line Diagram or Single Line Diagram (SLD) is a simplified graphical representation of the power system that is the interface for creating and managing the electrical networks include circuit breakers, transformers, capacitors, bus bars, and conductors. The One Line Diagram is the starting point of the power system analysis and other electrical design and engineering works that shows interlocks, inter tripping, system capacity, Voltage levels, currents, impedances, generation power levels etc. The One Line Diagram is a key deliverable document of the Detailed Design and Engineering developed by an Electrical Engineering discipline.
