Answer Posted / raj(b.e.electrical)
e1/e2=e3/e4
230/12=400/e4
e4=400/19.16667
e4=20.869v
so ans is : 20.869v
freq remain same.

ELECTRICAL DRIVES: can a motor load system with passive load torque can have equilibrium speed in second quadrant
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?
