disadvantage of A.C. transmission system
- the volume of copper used is much more than the D.C. system
- the inductance and capacitance of the line effects the rgulation of the line which is increased
- due to skin effect the line resistance is increased which further increases the skin effect
- the A.C. transmission lines are more effective to corona than D.C. lines
- in an A.C. sytem the speed of the generator and alternators is not economical, variation of these speeds must be controlled within very low limits
- in cable the alternatin current cause sheath loss.
- the construction of the transimission lines is not so easy as in case of D.C. lines
- the alternator must be synchronized, before they are made to run in parallel
