← TechnologyWhich outcome arises when a single-phase load is connected unevenly across a three-phase power distribution system?
A)Increased neutral conductor current flow✓
B)Elevation of the system's operating frequency
C)Harmonic distortion reduction in the grid
D)Enhanced transformer core saturation
💡 Explanation
When a single-phase load unbalance occurs, current imbalance causes increased neutral current flow because each phase carries a different current. Therefore increased neutral current results, rather than changed frequency, harmonic distortion reduction, or core saturation, each requiring distinct system faults or configurations.
