Function of Substation:


     Electric substation refers to the place where voltage and current are transformed, electric energy is received and distributed in the power system.

   The main function of substation is to connect the power grids with different voltage levels, and complete the task of power transmission and distribution through transmission lines.
   Generally speaking,The power generated by the power plant is boosted to the power grid through the step-up substation. After the power grid sends the power to the destination, it is depressurized and distributed to users through the step-down station.
