Electrical Engineering Symbols

About Electrical Engineering Symbols

The electrical circuit is a text that describes with certain characters the content and operation of an electrical device or a complex of devices, which allows to express this text in a short form.

In order to read any text, you need to know the alphabet and reading rules. So, to read the diagrams, you should know the symbols - the symbols and the rules for deciphering their combinations.

The basis of any electrical circuit is represented by conventional graphic symbols of various elements and devices, as well as connections between them. The language of modern schemes emphasizes in symbols emphasizes the main functions that the element depicts in the scheme depicted. All the correct conventional graphic symbols of the elements of electrical circuits and their individual parts are given in the form of tables in the standards.

Conditional graphics are formed from simple geometric shapes: squares, rectangles, circles, as well as from solid and dashed lines and points. Their combination of a special system, which is provided by the standard, makes it possible to easily depict everything that is required: various electrical apparatus, instruments, electrical machines, lines of mechanical and electrical connections, types of winding connections, type of current, character and methods of regulation, etc.
