Regulation =(Obtained voltage per phase - rated voltage per phase)/rated voltage per phase *100
The higher voltage it transformed to a lower voltage by the use of a step down transformer.
6350.8 volts AC rms. The phase to earth voltage is ( square root(3) ) x lower than the phase-phase voltage on a 3 phase system.
In British standard voltage classified Low Voltage( up to 1000 v (1 kv) medium voltage 1001 v to 10000 v ( 1.01 kv to 10.99 kv) High voltage 11kv to 66 kv and Ehv 66.1kv and above.
It is better to check the BDV (Break down voltage) of the oil to decide whether the said oil is usable for 11KV application, instead of depending upon its "expiry" date.
switchgear is electrical equipment regulats from electricity
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
i think 11kv per insulator

High voltage reduces the amount of energy wasted in transmission lines.
6350.8 volts AC rms. The phase to earth voltage is ( square root(3) ) x lower than the phase-phase voltage on a 3 phase system.
Yes. But,circuit breaker are usually rated in terms of current they can interrupt,not the voltage.
220v, 415v, 6.6 kv, 11kv,33kv,132kv,400kv
The test equipment used to test high voltage cables is a hi-pot test where a high DC voltage is a applied to the cable. This voltage can be from 150% to 200% of the working voltage of the cable.See related links below.
Depends on the sub station. It could be 11KV, 33KV, 66KV,110KV, 220KV, 400 KV etc
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.
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
