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.

Hello everyone, somebody knows what is a "surplice power" ? The hole phrase is: "This rating is appropriate for a generator set paralleled with an infinite bus e.g. a national electrical supply network or grid where the generator set is run at 100% load, 24 hours a day, 365 days a year and any surplice power is exported into the grid" Thanks in advance.
