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.

Why is the rating of transformer is like 11kv 33kv 66kv?
Because the tranformer calculation for ratings is calculated with the formfactor which is 1.11 constant. Regards Mithin kudva
What is 11kv Switchgear?
switchgear is electrical equipment regulats from electricity
What happen when you use 6.6kV instead of 11kV surge arrester?
The 6.6KV device will conduct before the 11KV device, quite possibly even in normal operation. Don't use it this way!
How is 11kv convert to 230v?
The higher voltage it transformed to a lower voltage by the use of a step down transformer.
What is the cable size that are used in 11kv system?
It depends on the power rating of the circuit but a common size would be 95 sq. mm up to about twice that. 11 kV systems are usually 3-phase 3-wire. Underground cables use copper while overhead ones tend to use uninsulated aluminium or aluminium conductor steel reinforced (ACSR) cables.
For a 18mw generation at 11kv what shall be mva rating of the 1133kv generator transformer?
I think, you are talking about a 11/33KV Transformer and by mistyping same has become 1133KV. However, rating shall be on the basis of 18MW +Loading factor . A 25/31.5MVA rating shall take care of of all these.
How much must be the distance between two conductors of 11kv line?
600mm is the distance between two conductors in 11kv line

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.
What instrument you use to measure 11kv?
A digital voltmeter with a range up to 11kV would be suitable for measuring a voltage of 11kV. Ensure the voltmeter is rated for the high voltage to be measured and follow safety protocols when working with high voltage systems.
What kind of wire transmit 11Kv power and is this different from those transmitting 415v power?
Insulation level is different between the cables.
What is the minimum value of Ir test in 11kv cables?
4444
What is 11kv Switchgear?

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
What is the base mva of 33Kv?
750MVA to 1000MVA for 33kV and 350MVA for 11kV
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
