Advantages of D.C. transmission of power 

1. It needs only two conductors as compared to three for a.c. transmission.

2. There is not an inductance, capacitance, phase displacement and surge problems in d.c. transmission.

3. Because of  the absence of inductance, the voltage drop in a d.c. transmission line is less than the a.c. line for the similar load and sending end voltage. For this reason, a d.c. transmission line has better voltage regulation.

4. There is no skin effect in a d.c. system. Thus, entire cross-section of the line conductor is utilized.
