← TechnologyWhich risk increases when a three-phase power transformer's neutral connection becomes unstable within a distribution system?
A)Increased circulating currents overheating windings
B)Elevated voltage imbalance damaging equipment✓
C)Reduced transformer efficiency at light loads
D)Higher harmonic distortion affecting grid stability
💡 Explanation
When a neutral connection becomes unstable, impedance increases, leading to unequal phase voltage distribution because current flow becomes unbalanced across phases during load variations. Therefore elevated voltage imbalance is likely, rather than circulating currents, reduced efficiency, or harmonic distortion, which relate to different electrical distortions.
