Transmission of Electricity

Q: Why the voltage is stepped up before transmitting electricity over a long distance?

A: Stepping up the voltage can reduce the current in the cable. This reduces the power loss in the cable during transmission.

Problems Involving Electricity Transmission.

  1. Power Loss During Transmission.
  2. The high voltage transmission cable is very dangerous.
  3. The cost of the cables is high.
  4. Charge leakage may happen between cables and earth.
  5. Pylons may be struck by lightning.
  6. Pylons and cables may be struck by light aircraft.
