A running three-phase motor loses one phase. What condition is likely?
- Severe current imbalance and overheating
- BHigher insulation resistance with no load effect
- CBalanced current at lower temperature
- DAutomatic creation of a neutral
Why A is correct
Single phasing can leave the motor turning while the remaining phases carry damaging current and torque falls. Proper overload and phase protection plus prompt diagnosis limit winding damage.
