Figure 12 Schematic of a Car's Electrical Circuit
When dealing with a large power distribution system, a special type of schematic diagram called
an electrical single line is used to show all or part of the system. This type of diagram depicts
the major power sources, breakers, loads, and protective devices, thereby providing a useful
overall view of the flow of power in a large electrical power distribution system.
On power distribution single lines, even if it is a 3-phase system, each load is commonly
represented by only a simple circle with a description of the load and its power rating (running
power consumption). Unless otherwise stated, the common units are kilowatts (kW). Figure 13
shows a portion of an electrical distribution system at a nuclear power plant.
