Layout Diagram Of Electrical Substation

The first step in planning a substation layout is the preparation of a one line diagram which shows in simplified form the switching and protection arrangement required as well as the incoming supply lines and outgoing feeders or transmission lines.

Layout diagram of electrical substation. While individual utilities may have their own format there is a high degree of standardization of these types of drawings worldwide for contractual and tendering purposes. The substation is the part of an electrical supply system which transmits the high voltage from the generating substations to the local distribution networks. The single line diagram of an 11 kv substation is shown in the figure below. Substation layout diagrams provide scale drawings of the location of each piece of equipment in a substation in both plan and elevation.
