1 2151in 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?

If we connect a motor and generator together (I mean that the generator gives the motor electricity and the motor gives the generator movement) regardless the losses. Will the generator still generate and the motor still move?
3 phase Motor will be given 2 phase after 2 to 5 second we given 3rd phase so Motor Run sum-time in forward or sum time run reverse direction. All time phase sequence is not change. Why motor run in reverse direction? Please Explain........
