Electrical Symbols — Power Sources

A voltage source is a two terminal device which can maintain a fixed voltage. An ideal voltage source can maintain the fixed voltage independent of the load resistance or the output current. However, a real-world voltage source cannot supply unlimited current. A voltage source is the dual of a current source. Real-world sources of electrical energy, such as batteries, generators, and power systems, can be modeled for analysis purposes as a combination of an ideal voltage source and additional combinations of impedance elements. 26 libraries of the Electrical Engineering Solution of ConceptDraw DIAGRAM make your electrical diagramming simple, efficient, and effective.

Design elements - Rotating equipment

The vector stencils lybrary "Rotating equipment" contains 55 symbols of rotating equipment: converters, generators, motors, rotating machines, and their parts and labels.
Use to design systems containing rotating electrical equipment (i.e., motors), armatures, brushes, and related mechanical devices ( brakes, gearing, clutches, interlocks).
"The academic study of electric machines is the universal study of electric motors and electric generators. By the classic definition, electric machine is synonymous with electric motor or electric generator, all of which are electromechanical energy converters: converting electricity to mechanical power (i.e., electric motor) or mechanical power to electricity (i.e., electric generator). The movement involved in the mechanical power can be rotating or linear.
Although transformers do not contain any moving parts they are also included in the family of electric machines because they utilise electromagnetic phenomena.
Electric machines (i.e., electric motors) consume approximately 60% of all electricity produced. Electric machines (i.e., electric generators) produce virtually all electricity consumed. Electric machines have become so ubiquitous that they are virtually overlooked as an integral component of the entire electricity infrastructure. Developing ever more efficient electric machine technology and influencing their use are crucial to any global conservation, green energy, or alternative energy strategy." [Electric machine. Wikipedia]

Building Drawing Software for Design School Layout

Classroom is the place where the pupils spend most of time, so it must to attract, arouse the interest, to be comfortable that the pupils wanted to go here and to stay longer. The psychologists say that the look of a class greatly affects the children. The first important characteristic is a color, the correct choice of color palette for the training premise helps adjust pupils and students on the right mood, promotes a thinking, activity, creativity and concentration. The most favorable colors are yellow, peach, beige, they attract attention and stimulate mental activity. As for the desks and other furniture, they should to be safe, quality, and to be arranged taking in account the room's size, lighting and age of pupils. For the primary classes are perfectly suited various illustrations on the walls. Use ConceptDraw DIAGRAM building drawing software tools and vector design elements from School and Training Plans solution for development School layouts and floor plans, furniture and equipment plans for School or Training offices, Design plans for classrooms, auditoriums and cabinets.

Electrical Symbols — Switches and Relays

In electrical engineering, a switch is an electrical component that can break an electrical circuit, interrupting the current or diverting it from one conductor to another. The mechanism of a switch may be operated directly by a human operator to control a circuit (for example, a light switch or a keyboard button), may be operated by a moving object such as a door-operated switch, or may be operated by some sensing element for pressure, temperature or flow. A relay is a switch that is operated by electricity. Switches are made to handle a wide range of voltages and currents; very large switches may be used to isolate high-voltage circuits in electrical substations. 26 libraries of the Electrical Engineering Solution of ConceptDraw DIAGRAM make your electrical diagramming simple, efficient, and effective. You can simply and quickly drop the ready-to-use objects from libraries into your document to create the electrical diagram.

Electrical Symbols — Semiconductor Diodes

In electronics, a diode is a two-terminal electronic component that conducts primarily in one direction (asymmetric conductance); it has low (ideally zero) resistance to the flow of current in one direction, and high (ideally infinite) resistance in the other. A semiconductor diode is a crystalline piece of semiconductor material with a p–n junction connected to two electrical terminals. Today, most diodes are made of silicon, but other semiconductors such as selenium or germanium are sometimes used. 26 libraries of the Electrical Engineering Solution of ConceptDraw DIAGRAM make your electrical diagramming simple, efficient, and effective. You can simply and quickly drop the ready-to-use objects from libraries into your document to create the electrical diagram.

Site Plan

Electrical Symbols — Transformers and Windings

A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. Electromagnetic induction produces an electromotive force within a conductor which is exposed to time varying magnetic fields. Transformers are used to increase or decrease the alternating voltages in electric power applications. 26 libraries of the Electrical Engineering Solution of ConceptDraw DIAGRAM make your electrical diagramming simple, efficient, and effective. You can simply and quickly drop the ready-to-use objects from libraries into your document to create the electrical diagram.
