You reduce voltage drop by increasing conductor size. As a general rule, if you believe you have a voltage drop problem, install the next size larger conductor.
Voltage drop can be calculated using the formula E=IR, where I is the anticipated current required by the load, R is the resistance of the conductor, and E is voltage, or in this case is voltage drop. If the answer for E is more than 3% of the circuit voltage or 5% of the service voltage, you need to increase conductor size.

AnswerBy increasing the supply voltage of the transmission line. This is why very high voltages are used in electrical transmission systems.
As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

To reduce power losses in transmission lines the voltage is made?
Much higher.
Why are transformers used to increase the voltage before transmission?
Using a higher voltage reduces power losses during transmission.
What is the need of extra high voltage transmission?
You want to deliver power as efficiently as possible. For the same input power, the higher the voltage, the lower the current required. The lower the current, the lower the ohmic power loss (R * I^2) during power transmission in the electric cable.Answerallows the use of conductors of practicable sizeeconomics (less volume of copper)reduce voltage drop along linereduce energy losses along line
What are the advantages of 750Kv high voltage?
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!
Electricity in power stations is generated at 25 000 volts why is it transmitted across the National Grid system at 132 000 volts?
Voltage is stepped up to higher voltages for transmission in a power transmission system in order to reduce the current required to deliver a certain power and, as a result, to reduce the size of the conductors required. Remember that power is current times voltage, so increasing the voltage allows a reduction in current for the same amount of power. Also, remember that the size of the conductor is proportional to the amount of current alone. At the receiving substation, the transmission level voltage is stepped down to a distribution level voltage, typically in the range of 11 to 13KV. It is then stepped down to service level voltages at the local distribution transformer serving a business or a group of residences.
Why is the voltage stepped up before transmission?
Voltage is stepped up during transmission to reduce the power loss during transmission due to resistance. Power is a product of Voltage*Current, and losses due to resistance are directly proportional to the square of the current. Now when we increase the voltage , keeping the power constant, the subsequent current reduces.. thus in turn reducing the transmission losses.
To reduce power losses in transmission lines the voltage is made?
Much higher.
Why are transformers used to increase the voltage before transmission?
Using a higher voltage reduces power losses during transmission.
Are transmission power cables capacity designed by voltage or by power is there any limit to the voltage that can pass?
Transmission power cables are designed by current carrying capacity.
Why kilo watts converted in kilo volts during transmission?
Power transmission lines by their nature have to carry power long distances. Since there is a voltage drop involved, the voltage is increased at the source so that the loss in the transmission lines still allow usable power to be delivered at the user location. The higher voltage is reduced by a transformer near your home to the standard 120 to 240 VAC.CommentYour question doesn't actually make any sense. Kilowatts aren't converted to kilovolts during transmission!
How do you reduce the Power dissipation?
Answer for mechanical systems:Use oil or grease to reduce friction!Answer for electrical systems:Making the voltage as high as possible is a good way to reduce power loss.ExplanationThe voltage drop along a conductor is proportional to the resistance and to the current carried. (V=IxR) So, for a given quantity of Power (W=VxI), if the voltage is made as high as possible there will be less current flowing and therefore less power loss.

Electricity in power stations is generated at 25 000 volts why is it transmitted across the National Grid system at 132 000 volts?
Voltage is stepped up to higher voltages for transmission in a power transmission system in order to reduce the current required to deliver a certain power and, as a result, to reduce the size of the conductors required. Remember that power is current times voltage, so increasing the voltage allows a reduction in current for the same amount of power. Also, remember that the size of the conductor is proportional to the amount of current alone. At the receiving substation, the transmission level voltage is stepped down to a distribution level voltage, typically in the range of 11 to 13KV. It is then stepped down to service level voltages at the local distribution transformer serving a business or a group of residences.
How a transformer is so important?
Transformers transform low vvoltages to hivh and vice versa. This is important in transmitting electrical power form the high voltage power plant to the low voltage home voltage. Using high voltage transmission reduces transmission power losses, I2R.
Which mode of transmission would result in less energy loss high current and low voltage or low current and high voltage Explain your reason?
low current high voltage power dissipation in power line = I2R the resistance of the power line is hard to reduce, especially when it is a long transmission line. but reducing the current through the line reduces losses as the square, a dramatic savings. reducing voltage would have no effect and would dramatically increase losses due to increase in current to try to deliver same power.
When voltage increases what happens to the amps?
the power will also increase as it is proved in my experiment
