  • The National Grid
    • Network of cables which distributes electricity from Power Stations to homes and other buildings.
    • Voltage = 32,000V or more! Transmitting electricity at a high voltage reduces power loss = efficiency!
    • Step Up transformers to step UP voltage to grid voltage
    • Step DOWN at local substations to step voltage down to suitable/safe use in homes/offices etc. (230V)
