Power houses uses high transmission voltage to supply places that are far away from the generation site. When in regards to distance the voltage is primary and the higher the voltage the greater the travel (using appropriate cable sizes etc). This voltage will suffer some loss during trans missioni but will arrive at its destination with a voltage drop that will not greatly affect the point of demand. keep in mind that this transmission is usually converted to Low voltage via a transformer before it is distributed to the end user.
Hope that helped:-)

If voltage and current are proportional why do they increase voltage in powerlines in order to decrease current?
Low current will equal low power losses due to the resistance of the cable. I squared R. (I is transmission current and R is resistance/Metre of cable) by increasing the voltage for the same amount of power the current decreases. Power transmission will take that advantage to transfer less current for the same amount of power.
Why do signs read Danger-High Voltage rather than Danger-High current?
Electricity is transferred with high voltage and low current to reduce transmission loss ( I2R , where R= resistance of wire). As high voltage is present in transmission lines, Danger-high voltage is written.
Advantages of SMPS over linear power supply?
1.Efficiency is high compared to linear power suplies 2.ripple voltage is very low 20mv. 3.constant regulating voltage is the one of the advantage of smps.
Electric power is transferred over large distances at very high voltages Explain how the high voltage reduces power losses in transmission lines?
The conductor used to transmit power has a specific resistance at the given power frequency. Power transmitted is equivalent to I^2 * R, so as the current increases, the power loss from the conductor also increases. To maximize efficiency, power is converted to very high voltages, which decreases the current, which minimizes the power lost in transmission.AnswerThe primary reason for using high voltage transmission lines is because, for a given load, the higher the voltage, the lower the load current. Low voltages would require cables of enormous cross-sectional area making transmission impossible, whereas high voltages allow the use of manageable-sized conductors. A secondary reason is the corresponding reduction in line losses -as described above.
What is the minimum value of high voltage?
Well, the word "high" can have different meanings in various work-areas. To an electronics specialist, "high" voltage can be anything above 5-10 V. To a home-electricity-technician, "high" voltage is anything above 50 V. To an electricity-company-technician, "high" voltage is anything above 230 V. It is better to ask for a clarification each time you here the term "high voltage".
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.
Why is high voltage a plus?
its because of transformers . they work with pulse
What does inductive load effect on High Voltage transmission line?
the inductive load which is generally use in high voltage transmission line known as transformer. the transformer transform the high voltage to low voltage.
High voltage transmission line in India?
ge transmission in india
Long distance transmission of electricity requires what?
High voltage.
What is distance protection in high voltage transmission lines?
your mothers gash
Why transmission is done on 11kv and 33kv?
High voltage reduces the amount of energy wasted in transmission lines.
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.
How can measure the voltage only seeing the insulators in a high voltage transmission lines?
i think 11kv per insulator
What are advantage of silicon control rectifier?
the big advantage is they are very low costthe big disadvantage is they can't be turned OFF
Why you use current source in data transmission?
A: The main advantage for a current source transmission is low source impedance. extraneous voltage influence is reduced by that characteristic.
What is hvdc power transmission?
'HVDC' stands for high-voltage, direct current.
