Industrial single line diagram. Now, lets go through a industrial single line diagram. When interpreting a single line diagram, you should always start at the top where the highest voltage is and work your way down to the lowest voltage. This helps to keep the voltages and their paths straight.
called a one-line diagram. A one-line can show all or part of a system. It is very versatile and comprehensive because it can depict very simple DC circuits, or a very complicated three-phase system. We use universally accepted electrical symbols to represent the different electrical components and their relationship within a circuit or system.
Figure 1 – Single-line diagram of transmission and distribution network. Central station where power is generated by 3-phase alternators. In Figure 1 C.S. represents the central station where power is generated by 3-phase alternators at 6.6kV or 11kV or 13.2kV or even 32 kV. The voltage is then stepped up by suitable 3-phase transformers for transmission purposes.

SmartDraw's electrical symbols connect to circuit lines automatically. To add a symbol to your electrical design, all you have to do is drag a symbol to a line and drop it. The line will split into two and connect each end to the symbol in exactly the right place. The symbol will stay attached even when you move the line around. Free Support
Overall plant single line diagrams show the electrical power distribution system, in simplified form, from the utility and/or generated supply to the load side of substation protection devices. Exceptions include substations 600 volts and over. The size of the power system determines the number of drawings required.Generally, the overall plant single line diagrams do not include breakdowns […]
