A power transformer is used in a substation to step-up or step-down the voltage. Except at the power station where a step-up transformer is used to step-up generation voltage to a high value (say 132 kV or 220 kV or more) for transmission of electric power, all the subsequent substations use step-down transformers to gradually

A high-voltage transformer is a device that converts high-voltage AC power to low-voltage AC power or vice versa.High-voltage transformers are mainly used for testing electrical equipment and components under high voltage conditions in laboratories or factories.They can also be used for power transmission and distribution,
Substations generally have switching, protection and control equipment, and transformers. In a large substation, circuit breakers are used to interrupt any short circuits or overload currents that may occur on the network. Smaller distribution stations may use recloser circuit breakers or fuses for protection of distribution circuits. Substations themselves do not usually have generators, although a power plant
A high-voltage direct current ( HVDC) electric power transmission system uses direct current (DC) for electric power transmission, in contrast with the more common alternating current (AC) transmission systems.
