Prefabricated Outdoor Power Distribution Substation is mainly used for AC 50Hz (or 60Hz), voltage 1000V and below the circuit, under the rated load can be continuous long-term work. Usually used in machine tools, mechanical equipment as electrical control lighting and light.
The control transformer is working with the electromagnetic induction principle. The transformer has two sets of coils. Primary and secondary windings. The secondary coil is outside the primary coil. When the primary coil through the AC, the transformer core to produce alternating magnetic field, the secondary coil to produce induced electromotive force. The turns ratio of the Satons transformer coil is equal to the voltage ratio.
