induction motor will be 5-8 times depend on drive ex-fan.
and coast for 6-8s to attain full speed.
so, the new contactor shall be good quality , with
overload,instantaneous with time delay shall be selected.
Reverse rotation protection, vibrations,
Unbalnced current protection optional.

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?
