A substation is?a high-voltage electric system facility. It is used to switch generators, equipment, and circuits or lines in and out of a system. It also is used to change AC voltages from one level to another, and/or change alternating current to direct current or direct current to alternating current.
#Primary Substation:
A step-up or primary substation is?used to distribute electricity over large distances. The primary substation receives power from a generating facility and amplifies the voltage through a power transformer. Power in a primary substation is transmitted through transmission buses to transmission lines.
#Secondary substation:
Secondary substations are?electrical infrastructures dedicated to the transformation of medium voltage to low voltage, as well as to the control and the protection of the electricity grid.
