If protection is proper then it will operate and stops the
motor. If there is no protection which is the normal case
in LT motors, then winding will burn there are two diffrent
pattern which will apear depending on the type of winding
connection i.e. delta or star.
You will find most of the winding failure in LT motors
happens due to single phasing.
