SLD

After Several Days of wondering what SLD stands for ?..I knew that stands for Single Line Diagram Which is Type or Plans and Diagrams used in Light Current Engineering ...

Thanks for Eng Yehia for Explanation

SINGLE-LINE DIAGRAM

The single-line diagram is used basically for the same purpose as the block diagram. When used with text material, it gives you a basic understanding of the functions of the components of a system.

There are two major differences between the single-line diagram and the block diagram. The first difference is that the single-line diagram uses symbols, rather than labeled blocks, to represent components. Second, the single-line diagram shows all components in a single line (figure 3-9). There are no interconnections shown for selected components as were shown on the block diagram (for example, alternator to voltage regulator and back to the battery). The single-line diagram is very simplified and should be used primarily to learn (in very broad terms) the function of each of the various components as a part of the total system.
