Answer Posted / prasad
It must be first understood here that the capacitor
current leads the voltage across capacitor & not the supply
voltage.
Whenever A.C. voltage is applied across the capacitor,
initially free electrons start conducting current offering
zero resistance & thus no voltage across the capacitor. As
the capacitor plates start getting charged (Polarity opp to
supply) it starts offering resistance to current & voltage
starts to appear across capacitor.

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?
