This is a complicated subject, and not really suited for the short answers provided on WikiAnswers. It also requires extensive pre-requesite knowledge which you may, or may not, have. Furthermore, there are different approaches to fault-level calculations. So, you should really refer to an appropriate textbook on this topic.

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
How can calculate HT cable size for 500mva transformer rating and voltage 11kv?
500Mw at 11kv works out to 45000 aa bit big for any wire manufactured on this planetsuggest you go to a more practical voltage like 132,000VAnswerSince we are inevitably talking about a three-phase transformer, the line current is determined fromIL= rated apparent power / (1.732 x UL) = (500 x 106) / 1.732 x 11 x 103)...which works out at 26 244 A which, as the original answer suggests, is not a practical value for this combination.
What is a HG fuse?
horn Gap fuse, used in 11kV & 33kV circuits to disconnect in case of fault.

How much must be the distance between two conductors of 11kv line?
600mm is the distance between two conductors in 11kv line
How do you calculate voltage regulation of 33kv and 11kv distributions?
Regulation =(Obtained voltage per phase - rated voltage per phase)/rated voltage per phase *100
What is the advantage of using relays in am 11kv 3 phase distribution system?
Relays are used primarily for protection purposes and, not just for 11-kV systems, but for ALL high-voltage transmission and distribution systems. There are numerous types of protection systems, including overcurrent, earth-fault, etc., and in each case the purpose of the relay is to (a) detect the relevant fault, (b) apply the desired response characteristic to that fault (e.g. inverse-time, etc.), and (c) operate whichever circuit breakers are necessary to disconnect the part of the circuit in which the fault is occurring.
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 is the minimum value of Ir test in 11kv cables?
4444
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!

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
