Transformer substation, place of changing voltage. In order to transmit the electric energy generated by the power plant to a far place, the voltage must be increased, changed into high-voltage electricity, and then the voltage is reduced as required to the vicinity of the user, and the work of increasing the voltage is completed by a transformer substation. The main equipment of the substation is a switch and a transformer. The power substation is called as a small power substation according to different sizes. The transformer substation is larger than the substation. The substation refers to a step-down substation with voltage class below 110kV in general; the substations include "step-up and step-down" substations of various voltage classes.
A substation is an electrical facility in an electrical power system that converts voltage, receives and distributes electrical energy, controls the flow of electrical power, and regulates the voltage, which connects the electrical grids of the various levels of voltage via its transformers. The transformer station is in a specific environment; is a process of converting AC-DC-AC. Like submarine power cables and long-distance transport.
