Power current transformers convert (transform) the voltage amplitude of the incoming electricity without changing its frequency. They are used when it is necessary to obtain a current with a certain voltage value. This ability is widely used when it is necessary to deliver electricity from one object to another.
These devices are used to optimize the transmission of electricity over a long distance. The greater the voltage amplitude of the transmitted current, the lower the losses. But it must come to the consumer with a voltage corresponding to the original values. That is, it needs to be lowered again. This is the task performed by these devices. The process is as follows: transformers at the substation receive electricity from the generator. They increase the voltage amplitude and transmit electricity further. At the receiving substation, devices are installed that transform energy, reducing its voltage to the original value. In branched networks, a fairly large number of them can be installed. It is clear that by their purpose, power transformers are divided into step-up (installed at the beginning of the line) and step-down (installed at the receiving point).
They may differ in:
Modern devices can increase the voltage by 10,000 times. The price of a power transformer depends on all these parameters. Power transformers are installed at power generation facilities in various sectors of the national economy - in the utility, agricultural or industrial sectors.
