Which outcome arises when one phase conductor in a three-phase induction motor grid develops a high-impedance fault?

💡 Explanation

When one phase loses continuity, the motor operates single-phase because symmetrical three-phase currents instantly become unbalanced, leading to increased current in remaining windings hence overheating. The rotor overheating and the motor produces high levels of vibration and noise. Single-phasing results rather than acceleration, shutdown, or balanced operation requiring intact phases.
