Why we are use 11KV / 22KV / 33KV / 66KV / 110KV / 230KV /
440KV this type of ratio. why cant we use other voltage
ratio like 54KV / 99KV et.,

Answer Posted / prashant

these 11,22,33,66,110 figures are rms values

generated voltage = V (avg value)

then max value (3.14/2)V

rms value is {1/sqrt(2)}*max. value
=.707*1.57=1.11

Is This Answer Correct ?    14 Yes 11 No

ii) A shunt motor supplied at 230V, runs at 900 rpm when the current is 30A. The resistance of the armature is 0.4 ohms. Calculate the resistance required in series with the armature to reduce the speed to 600 rpm, assuming that the armature current is then 20A. [12]

in a solar power plant,we are going to step up the voltage 350V to 33kv, and to 132kv GSS. i want to ask that if it is possible that 315v/33kv is not possible because we also use 315v/11kv. or it should be 415v/33kv? is it effects generation or losses?  the second question is-generation is depends on LV winding? or LV winding design for generation voltage?
