Answer Posted / rvg
delta connected winding, one winding burnt off means, its
open circuited. So the motor will work as open delta system
and run normaly with non uniform torque.
The max. load that can carry will be reduced to 57.7% of
full load.
If the motor is connected through a phase faliure relay,
the relay will trip the total ckt.
