The voltage of the transformer substation

## Transformer substation voltage
Transformer substations are inconspicuous heroes of our daily life. They quietly and effectively transform the high voltage of electricity entering the power plants to lower, suitable for use in our homes, offices and enterprises. Without them, our life would be impossible, because it is the substations that provide an uninterrupted supply of electricity. But what is the voltage of the substation and why is it so important?
## different stresses - different tasks
The voltage at the substation is not a single value. At the entrance of the substation, the voltage is usually very high - hundreds of kilovolts. This is necessary for the effective transmission of electricity over long distances. Imagine a long and thin wire - the higher the voltage, the less energy loss during transmission. However, such high tension is dangerous for people and household appliances. Therefore, the voltage is reduced at the substation using transformers. They are similar to special converters that reduce the voltage to safe and convenient values ​​for use-6-10 kilovolts for industrial enterprises and 0.4 kilovols for our apartments. It is like the distribution of water from a huge reservoir through smaller pipes so that everyone can use it comfortably.
### The role of transformers in voltage regulation
Transformers at the substation play a key role not only in lowering voltage, but also in its stabilization. The network constantly experiences the load fluctuations: electrical appliances are turned on and off, energy consumption changes within a day. Transformers, due to their design, are able to compensate for these fluctuations and maintain stress at the right level. This guarantees the stable operation of all connected consumers, preventing overload and breakdown of equipment. In the case of significant voltage deviations, automatic control systems that support it within permissible limits are triggered.
### Safety and reliability of substations
The work of substations requires highly qualified personnel and careful maintenance. High voltage is life -threatening, so access to the substation is limited, and all work is carried out in compliance with strict safety measures. Regular equipment checks, timely repair and modernization - all this is aimed at ensuring uninterrupted and safe operation of substations so that we can calmly use electricity, without thinking about the complex processes taking place behind the scenes of the energy system.
