they step down the voltage from the transmission voltage to the distribution voltage - generally anything above 25000 volts is considered transmission, This is done using transfomers. The substation also provides relaying to protect the circuits and substation equipment in the event of a overcurrent or fault current. There may also be relays that can provide back up sources of power when the main source is interupted.
