Instruments and measurements in electrical circuits, electrical and electromechanical.
Electrical and magnetic circuits. Chains with distributed parameters.
Fundamentals of analog and digital electronics.
Electromechanics. Transformers.

A complete list of laboratory works for each laboratory installation of the "Electrical Engineering" section is presented in the catalog and covers the entire range of topics required by educational standards.

For electrical engineering, they are produced in the following versions: bench, monoblock, mini-modular, manual (not automated), computer. Purpose, composition and price laboratory benches for electrical engineering specified in the price list (it is specified and supplemented monthly).

Circuit solutions, information and software and methodological support allow students to acquire and consolidate the necessary knowledge, develop practical skills in comfortable modeling and selection of the composition and changes in the parameters of typical electrical, electronic and electromechanical devices and circuits.

Stands for electrical engineering and electronics from the manufacturer

Laboratory stands for electrical engineering Uchtech-Profi firms have positive differences and advantages:

Ergonomics, reliability, modern design with an optimal price-quality ratio.
An extended range of modularity and unification of dimensions allows you to quickly and cost-effectively change the composition and configuration depending on the required laboratory work.
Each modification of the electrical engineering stand is an optimal configuration corresponding to the topic under study: generators, devices, electrical circuits, electrically conductive units, a digital phototachogenerator, a laboratory table, power cables, a set of connecting wires, teaching aids and information support (tablets, posters, animations, emulators).

The type and characteristics of related equipment depend on the list of laboratory works.

Implementation of the possibility of comfortable assembly of the circuits under study, setting the necessary parameters of the elements under study, setting up devices, control signals, retrieving and processing information.
Availability design feature, which allows you to remove the monoblocks from the frame of the table and use them independently as separate laboratory stands (tabletop version).
The availability of computer versions of training stands in electrical engineering also allows you to study time diagrams for various purposes (oscillography of transients, removal of statistical characteristics ...).
The exclusivity of the modification with the manufacture of educational equipment on an individual order: new laboratory work, laboratory equipment with a minimum m2, the specifics of training in training centers of industrial enterprises.
Visualization of results with the possibility of studying the effect of changing additional parameters, for example, an industrial source (network) on the object under study, established asymmetry in 3-phase electrical circuits, oscillations, voltages, introduction of higher harmonics into the network generated by load nonlinearity, etc.
Possibility of researching anomalous modes, elements (short circuits, exceeding the maximum allowable voltages and currents) without the realization of their irreparable breakdown.
Unconditional and comprehensive protection of the stand as a whole against overloads and short circuits, and trainees from the consequences of unprofessional treatment. So, for example, the study of various electrical circuits, including three-phase ones, is carried out with low voltage(10 - 15 V) galvanically isolated from the network.
Industrial and serial production for many years, taking into account the comments and additions of customers.
Post-warranty support, Maintenance and modernization.
Long-term (more than 17 years) experience in reliable deliveries for the execution of contracts in the market of Russia and the CIS countries (more than 1900 universities, technical schools and colleges). Particular attention is paid to the creation and development of an interactive sphere of technological development, which is ensured by the use of interactive demonstrations, existing laboratory and information equipment, interactive software and electronic educational process of active forms of organizing a laboratory workshop.

Electrical engineering tutorials

An exclusive set of information support in the form of posters, tablets, sections and interactive (electronic) visual aids contributes to the increase in the efficiency of the laboratory workshop. The latter are intended for demonstration through a projector on a screen or interactive whiteboard. All graphic material (animations, videos, 3D models, drawings, diagrams, tables, charts…) is carefully designed, structured and divided into topics in the form of “reference signals”. The built-in shell has a table of contents for viewing and managing interactive objects, or images.

Physical phenomena occurring in an electric and magnetic field are considered, methods for calculating direct current circuits, alternating single-phase and three-phase current, sinusoidal and non-sinusoidal current, as well as methods for measuring the parameters of electrical circuits. Examples and problems with solutions are given.
Corresponds to the current Federal state educational standard of secondary vocational education of a new generation.
For students of secondary vocational education in electrical power and electrical specialties.

Electricity. Electrical conductivity.
All substances are made up of atoms. An atom contains a nucleus around which electrons with a negative charge revolve. The nucleus of an atom contains positively charged protons and electrically neutral neutrons. Figure 2.1 shows a simplified model of the hydrogen atom.

If the number of electrons is equal to the number of protons in the nucleus, then the atom is electrically neutral. If an atom loses one or more electrons, it acquires a positive polarity and becomes an ion. But if an atom gains one or more electrons, then it becomes a negative ion.

For an electric current to occur, three conditions must be met:
1) the presence of free charge carriers (electrons in metals, ions in electrolytes);
2) the presence of an electric field in the conductor;
3) the presence of a closed circuit.

To understand how electric current flows through wires, let's recall the electronic theory of the structure of metals: positively charged ions oscillate near the nodes crystal lattice metal. Electrons seem to float between them in a chaotic motion, forming an “electron gas”.

When a conductor is connected to a source of electrical energy, the electrons begin to move in order, and an electric current arises. We cannot directly observe the electric current. The passage of current is judged by its action - thermal, magnetic and chemical.
