A few, at least. There are probably more. First, since the frequency is zero, reactive losses due to cable inductance are eliminated. Next, possible health risks due to alternating magnetic fields are reduced. Also, the non-trivial problem of syncronizing two power grids is eliminated. The DC is syncronously converted back to AC at the receiving end's phase and frequency, without regard to the generating end. Another possible benefit (from my point of view at least) is that HVDC systems are, to my knowledge, almost always run underground, eliminating unsightly transmission towers and lines.
The main advantage is that it's very easy to step alternating current up or down in voltage by the use of a transformer. High voltage is preferred for long distance transmission because it cuts transmission loss.
the inductive load which is generally use in high voltage transmission line known as transformer. the transformer transform the high voltage to low voltage.
voltage is termed as electrical pressure. when high voltage is applied more is the movement of electrons. hence losses will be less. this is one of the major reason for which high voltage transmission is chosen.secondly due to high voltage the current will be less so as the conductor size
High voltage.
'HVDC' stands for high-voltage, direct current.

its because of transformers . they work with pulse

1. Very high power transfer capability. 2. Very high controllability.

A high voltage like 750kV is used in transmission lines because this reduces the current in the wires for a given amount of power. A reduced current will reduce the power lost in transmission (I^2R).CommentFar more importantly than reducing line losses, it reduces the voltage drop along the line which would, otherwise, be enormous!
The length of the wire causes resistive load to be distributed along line. This accumulated resistance causes the voltage drop.AnswerThe voltage drop along a high-voltage transmission line isn't large in relation to the operating voltage of the line. One of the advantages (there are many) of using high voltages is that, for a given load, the line current is relatively low -so the voltage drop along the line is also relatively low.
High voltage.

High voltage reduces the amount of energy wasted in transmission lines.
