Understanding electrical diagrams/drawings
Before we start to learn how to draw schematics with CAD, let’s get an understanding of the various types of electrical drawings/diagrams you are likely to come across in industrial automation and control.
Common electrical drawings/diagrams in industrial automation and control include the following:
- Schematic diagrams can be referred to as electrical diagrams that show the components in a circuit using standard symbols and also how they connect with each other but do not include where the components and wires are located in the real system or device:
Figure 6.1 – Schematic diagram of a Direct On-Line (DOL) starter
- Wiring diagrams are electrical diagrams that show the components involved in a circuit, the physical connections between the components, and where the components and wires are located in the real system or device, unlike schematic diagrams, which do not show the real...
