Answer Posted / nishad
If we are connecting the HT motor in Star, the starting &
load current will be decrease 57% as compaire to Delta
connection.
In the cause of our HT motor (11KV - 780 FLA, 14MW)drawing
arround 4250 A at the time of starting. It's just equal to
6 times of full load current. as per manufactore, it's
locked rotor current is 4280A. so just think, what will
happened if that connected in Delta!!!!!
