The original idea was to add 10% to the nominal voltage to allow for a voltage drop in transmission. The voltages used in power transmission follow that tradition so that common transmission voltages are 11, 33, 132 and 275 kV, although voltage drops of 10% would be against the regulations in most countries now.
What else can I help you with?
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.
Why the generation voltage is 11kv not 10kv?
Alternator output voltages are typically restricted to around 25 kV to limit their physical size and the centrifugal forces to which they are subjected. In the UK, this voltage is then typically raised to 400 kV for transmission.The voltages to which you are referring to are typical of the voltages used in the UK's high-voltage distribution system. 'Grid' substations typically transform transmission voltages of 132 kV down to 33 kV (or, less commonly, 66 kV), and 'primary' substations then transform distribution voltages of 33 kV down to 11 kV.
How can measure the voltage only seeing the insulators in a high voltage transmission lines?
i think 11kv per insulator
What is Indian railway transmission line voltage?
220v, 415v, 6.6 kv, 11kv,33kv,132kv,400kv
Does the ac generator produce the 11kv or we get the 11kv via step up transformer?
I've seen AC generators that have output voltages from 120v to near 30kV. Likely you get your electricity from a large generator, that is connected to a step up transformer (few kV - 30kV stepped up to transmission voltage levels of 100kV - 750kV), which transmits the power through the bulk electric system, then down through step down transformers, through subT and distribution networks to your home.
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.

Why transmission is done on 11kv and 33kv?
High voltage reduces the amount of energy wasted in transmission lines.

Why is high voltage from 11kv onwards?
To be precise this kind of hi voltage is called distribution by power company. 11kv 16 kv that type of voltage. however transmission can be in the range of 5ookv. And you can see at tower from interstates lines
Why does corona effect is more in village than in city under transmission lines?
for sake of safety and protection the high voltage transmission lines are erected in less populated areas ie. villages , these lines have operating voltages about 220kv , 440kv , 132 kv( high tension lines) . while in cities the voltage is distributed at low voltages ( about 11kv(industry) , 440v residential ) because of safety issue . since corona loss highly depends on the operating voltage of lines thats why it is mostly seen in villages.

Why the generating stations produce 11kv voltage and it step up to 33kv during transmission.. why we should not use 230volts to generated and can step up to 11kv.. why?
if we take 11kv /33kv yhe current produced will be less when compared to 230v/11kv.. the curent produced will be gerater than 1000amp or above so the winding of the transformers will damage because thier is no winding at present to with stand the huge amount of current by K.B.N.GANGADHAR sasi institute of technology and engineering
Why Indian power system in multiples of 11kv?
Multiples of 11 kV are used in many countries. The idea is to deliver a round number of volts so you add on 10% to allow for line losses. So 10 kV becomes 11 kV. In practice lines are operated without a 10% voltage drop now because it represents an unacceptable waste of energy, but we have stuck with 11 kV etc. Common supply voltages used for area distribution are 6.6 kV, 11 kV, 33 kV, 66 kV and 132 kV.
Why electrical generation done on 11KV?
In most countries electrical power is generated at high voltages, such as 11 kilovolts.The reason for this is that it is much more efficient to generate and distribute electrical power at such a high voltage instead of at lower voltages.For more information please see the answer to the Related Question shown below: 'Why is electricity transported in high voltage but not in current?'.Another reason is something historical: in olden days when the electricity became popular, engineers had a misconception that there would be a voltage loss of around 10% in the transmission line. So, in order to get 10 kilovolts at the load point, they started sending 11 kilovolts from supply side. This is the reason. It has nothing to do with form factor (1.11).Nowadays that reasoning has changed and we are using 400V instead of 440V, or, in Europe and other 50Hz areas of the world, 230V instead of 220V.
