Transmission and distributionThe multitude of small generating plants that were progressively built has now been largely replaced by a few large plants interconnected with the various load centres by transmission lines operating at voltages up to 500 kV. The transmission lines terminate at 'bulk supply' substations adjacent to load centres, where transformers provide output at the nominated 'sub-transmission' voltage, of 132, 66, 33, 22 or 11 kV.'Distribution' is the term applied to the process of delivering power at a subtransmission voltage to 'zone sub-stations' and thence to consumers via 'high voltage' lines (usually 22 or 11 kV) to 'distribution sub-stations' for further transformation to 'low voltage' (standard at 415/240 volts) for the consumers service connections.
