System of cables & transformers linking power stations to consumers
Transfers electrical power from power stations to consumers
Change the potential difference
Increases the potential difference
Between power station and National Grid
P=V×IP = V \times IP=V×I (Power = Voltage × Current)
Current reduces
Less energy loss due to reduced current
Decreases the potential difference
Between National Grid and consumers
Consumer safety
Resistance of the wires
Use high P.D. (via step-up transformers)
