Always ON LOAD TAP changer is provied in HV side only.
Because HV side current is low and LV side current is high.
So, during on load tap changing losses will be reduced when
on load tap changer is in HV side.

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?
