← TechnologyWhich outcome occurs when a three-phase power system experiences ground fault impedance imbalance protection?
A)Neutral current increases excessively, causing overheating
B)Voltage becomes unstable causing a phase rotation
C)Equipment trips offline rapidly minimizing damage✓
D)Harmonic resonance amplifies damaging system oscillations
💡 Explanation
When ground fault impedance causes imbalance, sensitive detection trips breakers because the system rapidly detects the fault via differential currents, minimizing damage. Therefore, equipment trips offline, rather than overheating, unstable voltage, or harmonic resonance, which require sustained fault conditions or overload.
