← TechnologyWhich outcome occurs when a single-phase load is excessively high on one phase of a three-phase system?
A)Neutral conductor current overload✓
B)Transformer core magnetic saturation
C)System-wide voltage harmonic distortion
D)Increased reactive power compensation
💡 Explanation
When a single-phase load unbalances a three-phase system, excessive current flows through the neutral conductor because the phase currents no longer sum to zero, exceeding its capacity. Therefore neutral overload occurs, rather than transformer saturation causing heating; compensation changes; or widespread harmonic distortion which are less directly linked.
