Transformer substation is an electrical installation that is designed to receive /increase /decrease /voltage in the AC network, as well as for its correct redistribution, which will be used in the future by urban, rural, settlement and other facilities. The substation contains power transformers, devices that protect and control the substation in automatic mode, switchgear switchgear and other auxiliary structures required for the normal operation of the installation.
All transformer substations are divided into two large groups: those that increase the voltage and those that lower it. For example, transformer installations that step up voltage are usually built near power plants, and then convert the low voltage generated by the generators into a higher one. Buck kits work on the same principle, except they lower the input voltage, giving a lower reading at the output.
Also, all transformers operating to reduce voltage are divided into district, main step-down and local. Initially, district transformers receive voltage directly from the power transmission line, after which it is transmitted to the main step-down transformers, which can lower the voltage to 6, 10 or 35 kV. After the voltage is reduced, it will be transferred to local substations, which in turn lower it to 230, 400 or 690 V and distribute it among all end consumers of electricity.
A transformer substation is often completely assembled in specialized factories, and arrives at the end point in full assembly or in separate blocks, which are assembled after transportation.
