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!

Advantages of current transformer?
A CT allows:heavy currents to be measured using conventional ammeters, andelectrically-isolates the ammeters from high-voltage primary circuits.
Why is the voltage drop large in a high voltage transmission line?
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.
What are 2 advantages for this particular control voltage?
With voltage control there is so much voltage drop due to resistor, that's the disadvantage

Medium voltage is over 1000 v, high voltage is over 45 kV.
When was High Voltage Festival created?
High Voltage Festival was created in 2010.

How many voltage will pass through the high tension line?
It depends on the line, but AC high tension lines are typically between 100kV to 750kV while some DC high tension lines are as high a 1MV.Another AnswerVoltage doesn't 'pass through' a line. It appears between, or across, adjacent conductors. It's CURRENT that 'passes through' a line.
Advantages and disadvantages of automatic voltage stabilizer?
voltage stabilizer advantages and disadvantages
What are the advantages and disadvantages of such high 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
What are the advantages of power transformers over voltage transformers?
Power transformers can be used for power transformation. Voltage transformers are not suitable for high power applications.

What are the advantages of generating alternating Voltage for transmission?
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.
Advantages of ac generators over dc genrators?
The output of an AC generator can be stepped up with a transformer. The high voltage can be more easily transferred over longer distances with higher gauge wire. At the destination, the high voltage can then be stepped back down with another transformer.
