← TechnologyIn a three-phase electrical power distribution system, what outcome arises upon failure of neutral conductor connectivity?
A)Voltage imbalance between phases✓
B)Overheating of distribution transformers
C)Complete power outage for the system
D)Harmonic distortion in current waveforms
💡 Explanation
When the neutral connection fails, the neutral point floats because the load is unbalanced, causing unequal voltage distribution among phases. Therefore voltage imbalance results, rather than overheating, blackout, or distortion, which need fault current, overload, or non-linear loads respectively to manifest.
