Electrical engineering calculation programs. An overview of the best programs for drawing up electrical circuits A program for calculating electrical circuits using the loop current method

An electrician in the course of his professional activity very often has to perform many complex calculations of various parameters of electrical systems, depict electrical circuits, and select various equipment. This work takes a lot of time. There are many useful programs for electricians that are designed to calculate various parameters, draw diagrams, etc.

The main purpose of these programs is to greatly simplify the work of an electrician, minimizing the time spent on calculations or drawing diagrams, which is often faced by an electrical engineer. In this article, we will consider the most common programs for electricians.

Program "Electrician"

Let's start the review of programs with the multifunctional program "Electrician". The possibilities of this program are very wide. So, in this program you can:

Calculate the power of an electrical appliance using a known value of a single- or three-phase current, and vice versa, that is, knowing the electrical power, you can determine the current consumed, both a single-phase consumer and a three-phase consumer of electrical energy;

Determine the rated current and power for a given conductor cross section, taking into account the laying method, as well as other conditions;

Calculate the value of voltage losses in the network;

According to the given parameters, determine the required cross-section of the wire, cable (special cable);

Check the selected cable (wire) according to several criteria;

The Electrician program has an intuitive and user-friendly interface.

This program has many useful features that will be useful not only to an engineer, but also to a home master. For example, in this program, you can calculate the required amount of wire for laying electrical wiring in an apartment.

In addition to the great functionality of this program, one more advantage should be noted - it is absolutely free.

For information on how to work in the Electrician program, see here:

Program "Mobile electrician"

Nowadays, access to a computer is not always available, but a mobile phone is always with you. We bring to your attention another program for an electrician "Mobile Electrician". This program has many useful features that will be indispensable for both a professional electrician and an ordinary home master.

With the help of "Mobile Electrician" you can calculate the required cross-section of a wire or cable, select the necessary protection device, calculate the rated current of a particular wire (cable) and much more. A huge advantage is that this program will always be at hand, and at the right time you can easily calculate the required parameter.

Consider the following program - "Compass-Electric". This program is intended for the design of equipment and the further development of documentation in the electrical industry. This program greatly simplifies the process of creating documentation when designing various equipment, since most of the elements are generated automatically.

The program consists of two parts (modules): schema editor and database. The schematic editor allows you to create several types of circuits, ranging from a circuit diagram to a layout diagram of elements. This module also has the ability to create specifications, various tables for a visual representation of the ways of connecting certain elements of circuits, lists of elements used in circuits.

The database contains all the components that are used in the project. By default, this module of the program contains up to 6000 different types of products and several hundred graphic symbols that are used in the design of various equipment (low-voltage installations, automated supervisory control systems, various automation devices and relay protection). In addition, the user has the opportunity to import his database of symbols, finished products, their characteristics and much more.

Another program similar in scale and capabilities to Compass-Electric is.

The scheme is the main document of an electrician, which he is guided by when performing various works, both installation and repair. Currently, there are many programs with which you can draw diagrams. Consider the popular program for creating electrical circuits "sPlan".

This program is distributed on a paid basis, but it costs its money. In this program, it is very convenient to create a scheme of any complexity. The program has a very user-friendly interface, so it does not take a lot of time to master it. This product is widely used by both students and professional electricians.

In this program, a huge number of elements of electrical products are installed. Therefore, it is suitable for depicting circuits for various purposes and types. In "sPlan" everyone will find for themselves the necessary elements for the image of a particular scheme. A student can easily draw an electrical circuit of a lathe, an engineer - a single-line diagram of an electrical network, and a professional electrician - a diagram of the electrical wiring of an apartment.

In this program, it is possible to specify nominal data and other notes for each element of the electrical circuit. The process of creating a diagram in "sPlan" is fast and effortless: just select the desired element and simply drag it to the diagram area.

In addition to the above advantages of this program, one more thing should be noted - the ability to print large formats on a regular printer. That is, you can split the drawing in A1 format into several sheets of A4 format and then glue them together. This is very convenient when there is no way to print a large format.

An example of creating a scheme in the sPlan program:

Program "Beginnings of Electronics"

Consider another program - "The Beginnings of Electronics", which will appeal to novice electricians. This program is an electronic designer, which simulates the processes that take place in electrical engineering. That is, you can create an electrical circuit of varying complexity, measure electrical quantities. In general, everything that is performed in a real physical experiment. Only in this case you have an advantage: all experiments performed in the program are virtual, therefore they do not carry potential danger, such as conducting a real experiment in a laboratory.

The program "Beginnings of Electronics" will help to study the various laws of electrical engineering, the principles of the use of protective devices, as well as acquire practical skills in determining various quantities and studying various phenomena.

To date, drawing electrical circuits by hand on a leaf is no longer used by any experienced electrician. It is much easier, more convenient and clearer to draw up a project for the electrical wiring of a room on a computer through a special software package in Russian. However, the problem is that not all programs are easy to use, so when they stumble upon an inconvenient and, moreover, paid version of the software, most old-school masters simply discard the modern modeling method aside. Next, we will provide readers of the site with an overview of the simplest programs for drawing electrical diagrams of apartments and houses on a computer.

Free Software

There are not many Russian-language, easy-to-use and, moreover, free software for compiling single-line electrical circuits on a computer. So, we have created a small rating so that you know which programs are best for drawing power supply diagrams for houses and apartments:

1. . Oddly enough, but the most popular and no less important - a free program for drawing single-line electrical circuits on a computer is the Visio vector graphics editor. With it, even a novice electrician can quickly draw a circuit diagram of a house or apartment. As for the functionality, they are not as advanced as the software that we will provide below. Summing up, we can say that Microsoft Visio is an easy-to-use and at the same time free software for modeling electrical circuits in Russian, which is suitable for home electricians.
2. . A more professional software package for the design of power supply schemes for premises. Compass has its own database, which stores the names and ratings of all the most popular types of automation, relay protection, low-voltage installations and other circuit elements.

KOMPAS-Electric

In addition to the 7 programs provided for drawing electrical circuits, there are more than a dozen editors in which you can draw up a basic plan for the power supply of a house or apartment for free, but other programs have a more complicated interface or problems with the Russian version. We recommend that you give preference to representatives of this rating, so that in the future you do not waste time searching for cracks, user manuals, and the like!

Paid software

We reviewed free programs for drawing up electrical circuits on our own. However, you yourself understand that the paid versions provide a wider range of features and convenient add-ons that will allow you to draw an email diagram on a computer. There are many popular paid programs for drawing electrical circuits. We have provided some of them above, but there is one more program that is worth a little talk about - sPlan. It is one of the easiest to use yet feature rich software packages for wiring diagrams and tracing electronic circuit boards. The interface is convenient, in Russian. The database contains all the most popular graphic elements for drawing electrical circuits.

An electrical circuit program is a tool used by engineers to create electronic circuits for the purpose of calculating and testing products during the design, production, and operation stages. The exact display of the parameters is done using the scale. Each element has its own designation in the form of symbols corresponding to GOST.

Electrical Schematic Software: Why Do I Need It?

With the help of the program for electrical circuits, you can create accurate drawings, and then save them electronically or print them out.

IMPORTANT! Almost all programs for drawing diagrams have ready-made elements in the library, so you don’t have to draw them manually.

Such programs are paid and free. The former are characterized by great functionality, their capabilities are much wider. There are even entire CAD systems that are being successfully used by engineers all over the world. With the use of programs for drawing diagrams, the work is not only fully automated, but also extremely accurate.

Free programs are inferior in functionality to paid software, but they can be used to implement projects of initial and medium complexity.

The software makes your work easier and more efficient. We have prepared a list of popular circuit creation programs used by professionals around the world. But first, let's figure out what schemes are and what types they are.

Programs: for what schemes are they intended?

The scheme is a design document of a graphic type. It contains in the form of symbols the constituent components of the device and the links between them.

Schemes are part of the design documentation set. They contain the data necessary for the design, production, assembly, regulation, use of the device.

When are diagrams needed?

1. Design process. They allow you to determine the structure of the product being developed.
2. Production process. Provides an opportunity to demonstrate the design. On their basis, a technological process, a method of installation and control is being developed.
3. Operation process. With the help of diagrams, you can determine the cause of the breakdown, correct repair and maintenance.

Types of schemes according to GOST:

• kinematic;
• gas;
• energy;
• pneumatic;
• hydraulic;
• electrical;
• combined;
• optical;
• divisions;
• vacuum.

What is the best program to work with?
