Chapter 5 LO5 How Electricity Is Distributed Through The National Grid

Question 1

Explain how electricity is distributed through the National Grid

Answer 1

1. Power statioms generate electricity at 22KV.
2. This is stepped up to high voltage (275KV to 400KV) by transformers.
3. Electricity is transmitted at high voltage to reduce energy losses in wires.
4. Voltage is stepped down by transformers close to consumers.
5. Electricity is distributed to homes at 240V
