A.C. transmission.

The Benefits of ac transmission system are:

  1. The power can be produced at high voltages.
  2. The maintenance of a.c. sub-stations are simple and cheaper.
  3. The a.c. voltage can be stepped up or stepped down by transformers with ease and efficiency.
  4. This allows us to transmit power at high voltages and distribute it at safe potentials.

The Disadvantages of ac transmission system are:

  1. An a.c. line needs more copper than a d.c. line.
  2. The construction of a.c. transmission line is more complicated than a d.c. transmission line.
  3. Due to skin effect in the a.c. system, the effective resistance of the line is improved.
  4. An a.c. line has capacitance. Therefore, there is a continuous loss of power due to charging current even when the line is open.
