Electrical Symbols, Electrical Diagram Symbols

Drawing electrical circuit diagrams, you will need to represent various electrical and electronic devices (such as batteries, wires, resistors, and transistors) as pictograms called electrical symbols.

Traditionally these symbols may vary from country to country, but today they are standardized internationally to a large extent.

How to create Electrical Diagram using ConceptDraw DIAGRAM. Depending on type of electrical diagram it require variations of Electrical Symbols set. Most of symbols located in the libraries of Electrical Engineering Solution - electrical diagram symbols from the Industrial Engineering Area at the ConceptDraw Solution Park.

    Network Topologies →

    When describing any computer network, we imagine a set of devices and nodes, arranged in some way. Talking about network structures, we should distinguish physical and logical network topologies, as physical topology is about devices location and logical topology illustrates data flow. In the same time, they do not have to match, and some devices, such as repeaters, may have a physical star layout, but a bus logical topology. There are two main types of computer network topologies: Physical topology that show the physical organization of a network - equipment and types of connections. Star network topology involves a set of devices that is connected to a single hub (router). Ring network topology means that, devices connected according this topology have two connections, connecting with nearby devices to make a loop. Bus network topology is the topology presented at the current diagram. It is similar to a ring topology. The difference is that data moves up and down a linear connection, copying itself where network equipment works as bus-stations along the way. This network topology can be used for small network, or when adding an extra device into a network.Network Topologies

    Emergency Plan →

    Unfortunately, a man can’t predict the future and no one is safe from natural disasters, such as floods, earthquakes, hurricanes or fires. Nonetheless, what you can do to ensure safety for you and your relatives is to create an emergency plan, so everyone will know what to do if emergency happens. Keep that plan simple and train it several times a year so that no one could forget any details of it. Fire and emergency plans are important to supply people with a visual safety solution. This diagram presents a set of standard symbols used to depict fire safety, emergency, and associated information. Using clear and standard symbols on fire emergency plans provides the coherence of collective actions , helps to avoid embarrassment, and improves communications in an emergent situation. The fire emergency symbols are intended for the general emergency and fire service, as well as for building plans ,engineering drawings and insurance diagrams. They can be used during fire extinguishing and evacuation operations, as well as trainings.
