← TechnologyWhich problem arises when a long transmission line circuit utilizes excessive inductive reactance?
A)Ferranti effect increases receiving end voltage✓
B)Skin effect drastically increases line impedance
C)Corona discharge causes premature insulation failure
D)Proximity effect reduces effective conductor area
💡 Explanation
When excessive inductive reactance exists in the line, the Ferranti effect occurs because the charging current leads the voltage. Consequently, the receiving end voltage will be higher than the sending end, rather than increased impedance, insulation failure, or conductor reduction, which require different conditions.
