A three Phase motor is tripping out on load. The nameplate of the motor reveals a full load current of 168 A. When the motor is operating under load,an ammeter indicates the following: Phase A = 168 A, Phase B = 164 A, and Phase C =125 A. What is the most likely problem with the motor? Explain what must be done to clear the fault.
