In power engineering, a single-line diagram, also sometimes called one-line diagram, is a symbolic representation of a three-phase electric power system. The one-line diagram has its largest application in power flow studies. Electrical elements such as circuit breakers, transformers, capacitors, bus bars, and conductors are shown by standardized schematic symbols. Instead of representing each of three phases with a separate line or terminal, only one conductor is represented. It ... On a three line diagram, however, you can see the positive, negative, ground cables of a DC system, and L1, L2, (L3 on three phase) Neutral and Ground cables on an AC system. Each positive and negative line is represented as a single line. The connection from a PV module to an inverter is represented with only one line on a single line drawing, whereas the same connection is represented as three lines (positive, negative, ground) on a three line drawing.

A common example of a 3 phase power circuit to represent using a single line diagram would be the power transmission and distribution to the consumers. This diagram clearly shows a 3 phase power generating station that transmits the power to the consumers below.
