The equipment of the distribution device

## The equipment of the distribution device
The distribution device (ru) is the heart of any electric system, whether it be a small private house or a large industrial enterprise. Its task is a safe and effective distribution of electricity to various consumers. For this, a variety of devices are used that can be divided into several main groups. Understanding the principles of this equipment will help you better navigate in electrical engineering and ensure the safety of operation.
### Basic protection elements
Protection against overloads and short circuits is one of the most important functions of the ru. Here, circuit breakers (machines) come to the rescue. They instantly respond to the excess of the permissible current, tearing the circuit and preventing equipment damage and fires. More complex systems also use protective shutdown devices (RCD), which disable the power when the current leak is detected, protecting the person from electric shock. In addition, fuses are often installed in the ru who, although less smart than machines, also play an important role in protecting the network. The choice of a specific protective device depends on the parameters of the network and safety requirements.
### measuring instruments and control
For effective power management, it is necessary to control the network parameters. Ammeters, voltmeters and wattmeters showing current, voltage and consumed power, respectively, are installed in the ru. More modern RU are equipped with digital devices that can display more information and even transmit data to remote servers for monitoring. Such control allows you to quickly identify malfunctions and optimize energy consumption. Also used are electricity meters that record the volume of energy consumed.
## Complete equipment
In addition to the main elements, other devices that improve its functionality and safety can be installed in the ru. These include tires connecting various elements, various disconnectors that allow you to isolate individual sections of the network, and transformers that change the voltage. In some cases, automatic control systems are used, which allow you to remotely control and control the operation of the ru. The equipment of the RU depends on its purpose and requirements for safety and efficiency. The correct selection and installation of equipment guarantees reliable and safe operation of the entire power grid.
