If you work with electrical systems, chances are you’ve seen or worked with an electrical schematic drawing at some point.
Also known as circuit diagrams, electrical schematic drawings are crucial for mapping out the entire layout of an electric circuit. Freelance engineering design services and technicians rely on electrical schematic drawings to build and operate different systems. Without these drawings, they would be completely lost. Having a team or department to work on them is crucial.
However, many designers are already working hard in the trenches to support the rest of their firm’s operations. As a result, outsourcing this task might be the best way to go for your company.
Cad Crowd has a vast network of freelancers that can work on any project. By matching your team with one of our thousands of pre-vetted designers, we can ensure that you’re given the precise and accurate schematic drawings you need.
Electrical schematic drawings are used in a variety of industries and projects, including:
No matter what industry you’re in, acquiring a precise and accurate electrical schematic drawing is crucial for building and maintaining various systems. Every circuit must be drawn in complete accuracy to prevent any inconsistencies or mistakes from occurring later.
Electrical schematic drawings offer a variety of attractive benefits for companies. Industrial, mechanical, and electrical engineers all rely on them to determine how to connect all the components of a circuit system together.
A clean and carefully drawn-out diagram can help electrical engineering services identify and fix different problems in a system effectively and efficiently. Working with electrical schematic drawings can also help your team significantly reduce development time, thereby improving their productivity rate.
Circuit diagrams are also effective in building and maintaining a safe work environment for employees. Should an accident occur, your electricians can consult the system’s electrical schematic drawing to help them resolve any trouble that may have been caused.
To the untrained eye, an electrical schematic drawing might look like a jumbled mess of nonsense. But upon further inspection, you’ll find that a schematic drawing is actually quite logical in its layout.
Different symbols, arrows, and lines are added and arranged throughout the diagram to represent certain parts of the system. Together, they show viewers how a circuit’s components are connected electrically.
Schematic symbols may be used for components, such as a:
These symbols are typically accompanied by one or two letters that confirm the identity of the component they represent. For instance, R’s usually represent resistors and S’s are used for switches.
If you see a number next to a letter, this means that there are multiple versions of the same component in the circuit. For instance, you would label multiple resistors as R1, R2, R3, and so on. When you read a schematic, you’ll also see different lines connecting the various symbols. Nets and nodes are used to represent the relationship between different components in a circuit. Nets are straight lines.
Sometimes, an artist may distinguish a net from other lines by assigning a unique color to it. Nodes can be found at junctions and are created when wires get split into two different directions. Drawn as dots, nodes are placed at the intersection of different wires to show that they are connected to each other. If no dot is drawn, there is no connection between the wires. They are just passing by each other.
Designs do vary in complexity according to the specific project. Alternative symbols and variants may be used across different companies. For instance, the International Electrotechnical Commission and Institute of Electrical and Electronics Engineers each use a different set of symbols to represent the same components.
That’s why all of the members of the team must know how to assess and analyze an electrical schematic drawing. Otherwise, you may suffer from miscommunication and other issues that could delay the launch of your project.
Familiarizing yourself with different types of diagrams can also be extremely beneficial for you and your team:
CAD designers are typically well-versed in several different software programs. The most popular programs used by designers and firms include:
● TinyCAD: TinyCAD is a free, open-source program for drawing circuit diagrams. This popular program runs under Windows. It encourages sharing and collaboration by inviting designers to upload useful symbols that may benefit others in their drawings. You can find a support forum, symbol search, and various tutorials on their website. New versions of TinyCAD are also installed on a regular basis and can be downloaded for free.
● SmartDraw: SmartDraw is another free online CAD drafting software that is suitable for both beginners and experts. Many designers find it to be extremely user-friendly. With the program’s provided set of smart CAD tools, designers can easily adjust the dimensions and angles of different spaces in their diagrams. Within minutes, you can build a drawing using one of the many templates and examples provided for free. An extensive symbol library is also available for designers. Working with a big team? Your designer can easily share their work via Dropbox®, GoogleDrive®, Box®, or OneDrive®.
● Scheme-it: Scheme-it offers all of the resources and tools your team needs to build a proper electronic circuit diagram. Included in the progream is an electronic symbol library and a Digi-Key component catalog. Designers can also keep track of different parts used for a design with the program’s built-in materials manager. Scheme-it can be run on any major web browser without having to download any plug-ins. However, if you want to share and save any designs, you’ll need to register for a membership.
● AutoCAD: AutoCAD is another popular design software for creating 2D and 3D drawings. Users can download a free trial of the software. However, you will have to pay for the program on a monthly or yearly basis. A 3-year payment option is also available, and is considered to offer the best value for buyers. AutoCAD allows you to draft and design various 2D geometry and 3D models, automate tasks like counting or comparing drawings, and add apps and APIs to further enhance its use.
