Answer / bala_vlsi

No, because we can achieve the recommended motor torque
at 415 V+/- 10 % level only (torque is directly
proportional to the current (P = I²/R) If the torque is in
low condition, required more current for try to achieve
the specified torque so automatically the motor will
generate more heat and motor will be damage / burn .

Answer / j.karthik

The above answer is correct. While we can run the motor
using the 360Volt then the motor will rotate only the lesser
amount of speed than the rated 3000/1500 rpm. and it cannot
give sufficient output...and also produces a heat in the
motor winding.......

why we step down voltage level from 33kv to 11kv and 11kv to 415v.Instead we can step down voltage from 33kv to 415v directly using single transformer.
