Answer Posted / shyam prakash ray
The principal is to keep the starting current in safe limit
so that the motor achieves 70% of speed as connected to
star side, since the motor draws very high current at the
time of starting due to high starting torque.
Once the motor gets started then it is changed/converted
into delta side either manually or automatically for
running.

electrical ques
We have 5 Distribution sections with variable loads&We have 3 Gensets(500kva,380kva&250kva) our total load is between 400kva to 600kva. so how could we connect 3gensets.
we have a 2.5hp Starite electric motor water pump,the elec motor burned out,we need to replace starting capacitor(old capacitor specs erased),what microfarad rating capacitor do we need? 110-125V
