A switching station refers to a distribution substation that does not perform voltage transformation but uses switching equipment to open or close electrical circuits. A substation is a power facility in the electric power system that transforms voltage levels, receives and distributes electrical energy, controls the direction of power flow, and adjusts voltage. Think of it as a traffic interchange for electricity: it connects, disconnects, and redirects power flows, but unlike a substation, it doesn't step voltage up or. The substation also refers to the power supply and distribution facilities used to receive power and distribute power.
