- P1- National Grid
- Step by step
- Power stations
- Step up transformer
- National Grid system (132000v or higher)
- Step down transformer
- 230v to your home
- Step down transformer
- National Grid system (132000v or higher)
- Step up transformer
- Power stations
- Electricity is transmitted from power stations to homes through the National Grid/
- Power= Voltage x Current
- Step up transformers increase voltage to 400000V
- Increasing voltage in cables decreases current.
- wires heat up less.
- thinner cables used and less energy wasted.
- step down transformers reduce voltage.
- uses aluminium cables reinforced with steel, which conducts electricity well.
