List of parts of Power system.

• Generation, transmission and distribution.

• generation, transmission and transformer

• generation, impedance and distribution.

• Motor, transmission and distribution.

Electricity is distributed along…

• Direct current

• Alternating current

• Transmission lines

• Transformer

If the current is transmitted at high voltage...

• less energy is lost

• more energy is lost

• it produces alternating current

• underground cables are used
