A 33/11 kV substation is a type of electrical substation that plays a crucial role in the power distribution network. Its primary function is to step down the voltage from a higher sub-transmission level of 33 kilovolts (kV) to a primary distribution level of 11 kV. This lower voltage is then distributed to smaller substations or directly to large industrial, commercial, or residential areas. Essentially, it acts as a bridge between the high-voltage transmission grid and the local distribution network, ensuring safe and efficient power delivery to end-users.
