Power loss during power transmission is predominantly due to the current drawn, which heats the wires. Power dissipated is current x voltage and voltage is current x resistance, so in any wire with fixed resistance the power loss is proportional to the square of the current flowing. The higher the voltage you use to transmit the power down the distribution network the lower is the current, hence power is distributed at the highest voltage that is practical, then the voltage is dropped to the domestic level at the destination sub-station or by a transformer on the power line pole. Major distribution systems operate at over 100 kV, with regional ones at lower voltage.
Additional Answer33 kV (not 'kv'!) is the primary distribution voltage, not a transmission voltage, used in the UK. Other distribution voltages are 66 kV (not very common) and 11 kV. Transmission systems operate at 400 kV and 275 kV.

What ACSR conductor is used for 33kV transmission line?
Single Circuit PantherACSR Conductor
What is power transmission?
Power transmission is the movement of energy from its place of generation to a location where it is applied to performing useful work.
What is an example of a step-up transformer?
Power stations use step-up transformers to transmit power at a high voltage instead of a high current. This reduces the power lost in the transmission lines.
Why normally Generator rating are between 11Kv to 22Kv?
Because if we use a generator of 33kv or higher then the radii must be of 2-3 meters that is not good. And also the area of the generator will be very high and losses and heat paameters will also be high. The main point is that we use 11kv generator at power plants and we have to step up the power to 220KV or 500KV etc. So we use 11kv or 22kv instead of 33 kv or higher.. By doing so we save the cost of area required, radii of rotor, and losses produced by higher power generators.
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.
What are the effects of being at end of 33KV transmission line?
The effects of being at the end of a 33KV transmission line will result in a higher voltage. This is due to variation in the perameters that dictate how the transmission is sent and received.
Why transmission is done on 11kv and 33kv?
High voltage reduces the amount of energy wasted in transmission lines.
Why only 11kv is used in power systems transmission line?
It isn't. In the UK, transmission and distribution voltages are 400 kV, 275 kV, 132 kV, 66 kV, 33kV, and 11 kV.
What ACSR conductor is used for 33kV transmission line?
Single Circuit PantherACSR Conductor
Why 22kv 11kv 33kv 132kv 220 kv are standard transmission voltages in transmission lines why not 20kv 10kv etc?
Its just a matter of standard. In my area, for instance, we use 13.2 KV for distribution lines, and 69 KV / 138 KV for transmission lines.
What is Indian railway transmission line voltage?
220v, 415v, 6.6 kv, 11kv,33kv,132kv,400kv
What is the base mva of 33Kv?
750MVA to 1000MVA for 33kV and 350MVA for 11kV
Can you use power steering fluid in your transmission 87 Ford?
There is not much difference between power steering and transmission fluid. Many people use power steering in place of transmission fluid because it is cheaper.
Why transmission line voltage is like 6.6kv 11kv22kv 33kv etc?
Usage of such high voltages will increase the efficiency of the transmission lines and decreases the losses in the line. It also reduces the requirement of conductor size.
How do you use the word transmission in a senctence?
Wind power projects are undermined by transmission problems
What is electrical power transmission?
Moving electrical power from generating point to use point.
Can you transmission fluid for power steering?
Do NOT use transmission fluid in your power steering. It is designed for automatic transmissions, and a few rare manual transmissions only. (1965 Plymouth "Slant Six" manual transmission used automatic transmission fluid). In most Chrysler products made after about 2002, ATF is what they use for power steering fluid.
